(SIMP-10415) Honor build/rpm_metadata/requires (#169)

Before this patch, the project's RPM .spec file used a hard-coded
`Release:` number that could not be overridden by the optional
`build/rpm_metadata/release` file used by other projects.  The lack of
this capability prevents GHA pkg:single builds from tagging & building
pre-release RPMs for the assets  when PRs are still pending for final
release, which in turn prevents staging full yum repositories to start
testing the product install and dep resolution.

This patch adds support for `build/rpm_metadata/release`, and defaults
to the standard `-1` Release value.

This patch also
* Removes %{dist} from highline Release
* Removes %{dist} from Release
