archive_autodetect() match archive files before dir refs #66 #69 #73

Fix archive_autodetect() match patterns to detect archive files with higher
priority than a directory.

The upcoming git workflow will typically have the upstream repository as a git
submodule, seen as a directory. If the packager has configured source services
to generate an archive file in a supported format, or committed an archive file
from an upstream release, it should be detected first and used.

The packager can specify the archive explicitly via source service parameter if
they need to override (skip) archive_autodetect() logic.
