package/zfs: fix python3 support check
Backport an upstream commit fixing the python3 support check
"The 22.0 release of the python `packaging` package removed the
`LegacyVersion` trait, causing ZFS to no longer compile.
This commit replaces the sections of `ax_python_dev.m4` that rely on
`LegacyVersion` with updated implementations from the upstream
`autoconf-archive`."
Add a comment above ZFS_AUTORECONF.
