zfs_2_1: init at 2.1.13

This re-introduces the old stable ZFS version we had in the past following
the many predicted issues of ZFS 2.2.x series, that is much more stable
than any further ZFS version at the moment.

I am also removing myself from maintenance of any further ZFS versions as I am
planning to quit ZFS maintenance at some point.

In the meantime, for users like me who depend on ZFS for critical operations, here is a ZFS version
that is known to work for LTS kernels.
