gitlab/cerbero: Run gst-inspect on the built binaries

Also install Wine so that this can be done for cross-winXX jobs.

This will help do basic runtime checks for cerbero development. At some point we will want to make it so that all criticals/warnings by gst-inspect-1.0 while parsing plugins will be a hard error. Not doing this right now because some plugins are known to fail to load on native windows, and I don't want to create new blockers for our windows cerbero CI.
