btrfs-util: Make nested subvolume operations work unpriv

BTRFS_IOC_SEARCH is only available to root in the
initial userns. This means we fail to recursively
snapshot even if a subvolume has no nested subvolumes
at the moment.

Let's fix this by using the newer btrfs ioctls which
do work even if we don't have CAP_SYS_ADMIN in the initial
userns.
