Subject: Fix ZFS boot failure: set cachefile property after pool creation

- Add zpool set cachefile=/etc/zfs/zpool.cache after pool creation
- Without this, initramfs ZFS hook can't import pool at boot
- Causes "cannot import '(null)': no such pool available" error
- Add cachefile property test to full-test.sh
