Repair software release tests
-
slapos-master 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 slapos.core!317 (merged)
- gitlab 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
