            Minor fixes to os-release processing

Don't amend to the file if it's already present. When building locally
with `fedpkg local`, this results in the os-release file getting
progressively longer with each pass. Instead, truncate it and start
over.

Additionally, add os-release to .gitignore so it doesn't mark the
directory unclean.
