This change extends the garbage collector for the build cache server to
remove cached release artifacts. Release artifacts are copied to the
official mirrors and do not need to remain on the build cache after a
release was published.
By default, the 10 latest releases of all channels (including LTS and
previous LTS) are kept.
Also excluded from garbage collection are:
- Emerging new major releases (i.e. major number larger than the
latest Alpha release)
- channel progressions (major number exists in the lists of releases to
keep but minor is bigger than any release)
- patch releases (major and minor exist in list of releases to keep but
patch level is newer than in any release)
- SDKs (tarballs and containers) of any release in the list of releases
to keep; i.e. the SDK in <MAJOR>.0.0 for any release to keep.

gensub is a GNU extension; however, POSIXLY_CORRECT is enforced in
systemd-run which triggers gawk's traditional / posix mode.
Unset it before calling gawk to make gensub available.

This change adds a min_age parameter to the github CI SDK garbage
collector. The parameter specifies a minimum age (in days) for artifacts
to be garbage collected. NOTE that this can result in more artifacts
being kept than specified via the "keep" parameter if artifacts are
younger than min_age.
The change also has garbage_collect.sh pass the min_age parameter to
garbage_collect_github_ci_sdk.sh.
