Subject: [PATCH] fix: skip empty local-repository.tmpl in nodeset

When a pkgdir has no valid repodata, Yum.pm creates an empty
local-repository.tmpl file. Template.pm then reads it and generates
an empty yum repo config block in the kickstart. Adding a -s check
skips empty template files instead of silently including them.

Revives the fix from PR #4769 which was closed without merging.

Fixes #3572
