monitor-globalstate (which is supposed to create monitor configuration file
accessed by HTTP as .../public//monitor.global.json) runs by cron every 2
minutes. This crontab also uses randomsleep to add a delay - but there's a
promise waiting for this monitor configuration file to be available, so the
instanciation had to wait for this and if this was sometimes causing problems
in software release tests because promise did not succeed fast enough.

To prevent this pattern where slapos node instance has to wait for a crontab
to be executed, we run that script a first time from buildout.

Also improve the recipe `switch-softwaretype' by catching the possible errors.

This is based on commit "Firefox Version Up to 78.1.0esr", but it does not
replace the default firefox, just enable a new version for now.

This is a "minimal" version up to fix https://bugs.gentoo.org/580392 which
appears now that we build with gbm

some components, like binary chromium needs libgbm, which is part of mesa, but
build only when enabled.

* [slapos-master](https://nexedijs.erp5.net/#/test_result_module/20210629-DE509CB3/23) is failing in checkSoftware step, because:
  * wcfs is linked against system zlib (fixed in this MR)
  * the .so in the build directory have missing references. I think we don't need to check in build folders and also liblibgolang is missing, but it's not a problem because of the way we load dynamically at runtime, so I suggest changing checkSoftware in nexedi/slapos.core!317
* [gitlab](https://nexedijs.erp5.net/#/test_result_module/20210629-DE509CB3/10) is failing for some time because mimemagic have been yanked from rubygems. This is a minimal change to get the test running again, to prevent other problems to sneak in while we don't have tests

On wendlin.core 2, wcfs uses github.com/DataDog/czlib which uses zlib. We also
need to instruct linker to set a rpath for slapos' zlib, otherwise the system
one will be used.

Suggested by Kirill on !1007 (comment 136801)

Change all `check_port_listening` promises to `check_socket_listening`
and rename all associated `config-hostname` arguments to `config-host`

With recently backported fix for h5py

This software uses xml for parameters serialisation, so we can not use
boolean type. As a result, smtp_verify_ssl was always "true" and disabling ssl
verification was not working.

When accessing the smtp server from localhost, grafana attempt STARTLS and
verifies certificate, so scenarios of using localhost:25 as smtp server usually
needed smtp_verify_ssl="false".

Fixes and tests https://github.com/apache/trafficserver/issues/7880

By following:

https://docs.trafficserver.apache.org/en/9.0.x/release-notes/upgrading.en.html

configuration has been adapted.

Tests to new version string has been adapted with smaller fixes, including a
bit more time for log to appear in squid.log.

Previous patch is incorporated with 4f6bfe439e4ed7794992e16c16eb991976a3018e

The missing run was hidden by slow Caddy warmup procedure.
