Newer versions of xar for older OS versions fail to build on the build

I look to the build bots to determine if older OS versions can build a
new xar release, as my local development machine runs Sequoia, while I
also have machines running Tahoe, and one old MBP with Ventura (which is
rarely used and updated).
I’m always open to PRs and trac tickets when it pertains to supporting
older OS versions.
The primary issue right now is not which OS versions can build the
latest xar, it's that the version went backwards for some OS versions
after some users had already installed the newer version, and the epoch
was not increased. So xar never appears to be outdated for those users
and is not upgraded when the revision is bumped.
