gitlab-ci: pre-build containers to improve CI run time and reliability

Shaves about 50% off the build time on both debian and arch builds.
(yeah, I know, it's very small anyway compared to mesa, but we might
 want to add more things in the future)

This also makes the build no longer dependent on external websites:
once the image is build, only fdo-internal services are used.

+# This is the tag of the docker image used for the build jobs. If the

+#
+# In order to generate a new image, one should generally change the tag.
+# While removing the image from the registry would also work, that's not
+# recommended except for ephemeral images during development: Replacing
+# an image after a significant amount of time might pull in newer
+# versions of gcc/clang or other packages, which might break the build
+# with older commits using the same tag.
+#
+# After merging a change resulting in generating a new image to the
+# main repository, it's recommended to remove the image from the source
+# repository's container registry, so that the image from the main
+# repository's registry will be used there as well.
