gitlab-ci: Switch the container of the 'check-patch' & 'check-dco' jobs

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 using a
lightweight Alpine container, we can improve the runtime here quite a
bit, cutting it down from ca. 1:30 minutes to ca. 45 seconds.
