rpm: remove unused repo package build sources

Since commit git-lfs/build-dockers@d4c2fe6f79
the centos_script.bsh script in that repository has not built the
"repository configuration" or "repo" RPM packages, which were intended,
it seems, to contain extra packages and GPG signatures for Git LFS.

We can therefore remove the stale RPM spec and source files which
pertained only to this extra RPM build, and also some lines in the
rpm/build_rpms.bsh which created an empty stub GPG key file for this
build.
