fix(xcat-core): fold release-alias finalize into merge_core_repos

merge_core_repos already assembles the multi-arch core and runs the full
finalize tail (index -> sign -> final metadata -> write_release_alias, in the
required order so the xCAT-release-latest alias lands AFTER metadata and stays
out of the repo index). The preceding commit restored a separate finalize_core
sub purely to satisfy xcat_release_package.t, which grepped for
'sub finalize_core { ... $dir ... }'. That left two overlapping entry points:
--finalize-core (finalize one pre-assembled dir) and --merge-core-repos
(assemble N per-arch dirs THEN finalize) -- the former a strict subset of the
latter, with no in-tree or CI caller.

Consolidate on the single assemble+finalize path: inline the finalize tail into
merge_core_repos, drop sub finalize_core and the --finalize-core getopt/dispatch,
and update xcat_release_package.t to assert the stable alias is created after the
final metadata pass inside merge_core_repos ($out). Behaviour is unchanged (merge
already wrote the alias); only the redundant finalize_core interface is removed.
xcat_release_package.t 26/26; perl -c clean.
