main/zfs-rpi: upgrade zfs to 2.2.1 & drop armhf & armv7

ZFS 2.2.0 wants to make use of NEON SIMD. Such instructions are not
available in BCM2835, used in RaspberryPi 1 and Zero, that armhf target.

We should be able to target armv7, we do in zfs-lts, this is possibly an
issue with how we package linux-rpi.
