compact: support --cow/--no-cow switch

Users on btrfs may prefer to sacrifice performance for data
safety with RAID.  Allow them to do so by supporting the --cow
switch.  I missed this when I added --cow support to the other
commands.

Fixes: db671788 (support --cow switch to preserve CoW on btrfs, 2025-08-26)
