…izer binary This simplifies local development a little bit, but primarily will make it easier to move our Linux build into a build container with older glibc versions in order to support older Linux distros like CentOS 7.

Confirmed not just the reported glibc compat, but also actual compat with CentOS 7 via the |
…ndalone binary
Arranges for `pyoxidizer build` to run inside of a manylinux2014
container instead of on the ambient host, which yields the following
glibc minimum version improvements compared to our existing binaries
produced in CI (as reported by `pyoxidizer analyze`):
Minimum Version: 2.27 → 2.17
Minimum Distro Versions:
Debian 10 → 8
Fedora 28 → 19
OpenSUSE 15.3 → 12.3
RHEL 8 → 7
Ubuntu 18.04 → 14.04
The manylinux containers are readily available, well-maintained, and
designed exactly for this purpose. The standalone Python distributions
used by PyOxidizer are themselves limited to glibc ≥2.16, so we're now
basically at that limit! manylinux2010 versions are too old.
