reported that this component creates binaries that are missing missing
rpath because libzip cannot be found.

Also enable shared as it looks shareable.

Now this component can be shared.

Maybe newer versions of file in
https://github.com/file/file/commits/master/magic/Magdir/msooxml have an
equivalent fix and the patch is no longer needed. I have kept the change
minimal.

Most components depend on perl.

We'll use "go1.4-bootstrap-20171003.tar.gz, which contains the Go
1.4 source code plus accumulated fixes to keep the tools running on
newer operating systems." as described in
https://golang.org/doc/install/source#bootstrapFromSource

(this archive contains the "time: Skip TestParseInLocation test."

Using WSGI became the default behavior in
f4d141a1.

--user=root is redundant and it will break with MariaDB 10.4

This is important for performance and it enables testless promises.

Instantiation can be forced on manual action in the UI.

Remove method `generateHashFromFiles` in all file `test.py`, import it from `slapos.recipe.librecipe`.
