[RFC PATCH] gitlab-ci: Switch the 'check-patch' & 'check-dco' jobs to use python-container

[Thomas Huth <thuth@redhat.com>]

The 'check-patch' and 'check-dco' jobs only need Python and git for
checking the patches, so it's not really necessary to use a container
here that has all the other build dependencies installed. By installing
"git" in the python container, we can use this light-weight container
for these jobs instead.

 Mark as RFC since I'm not sure whether we want to have "git" in
 the python container or not?
