Hardcode the rpm-local-generator-support source commit.

And rebuild module for Ruby rebase.

Instead of using the /c\d+s/ branch,
we will hardcode the commit used for rpm-local-generator-support.

While c*s branch is OK to refer to for the workflows making use of
CentOS Stream first it complicates delivery for older EL releases.

In the case of a downstream module build, chances are that
the branches are named differently. But even if they are named
differently, we can use direct commit hash instead.
We make use of 2 properties here:
1) The git history of the branch is kept in sync
2) The rpm-local-generator-support does not have a reason to change
   often, or possibly at all, for the lifetime of the module.
