[Buildroot] [git commit] gitlab-ci: handle the defconfig build conditions in script

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=bca0f1bb415dcb1f26df2f7f6174367e821c6815
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Note that we do not propagate the existing comment, because it is
partially wrong; instead we just keep the per-condition comments.
