Report and patch from Wes Morgan.

The new version of ZFS in head defaults to not listing snapshots with "zfs list", which causes a problem with the "freebsd-snapshot" utility.

Fix: The new "zfs list" command requires "-t snapshot"
The fix  adds the correct zfs list command syntax to the existing /usr/local/sbin/snapshot and is backwards compatible.

Fix port by removing existing patch
/usr/ports/sysutils/freebsd-snapshot/files/patch-snapshot

and creating two separate patch files (patch-snapshot and patch-periodic-snapshot) which are attached:

Use snapshot tools with new zfs version in current.
