Remove requirement for -d 1 for zfs list and zfs get with bookmarks

df58307 removed the need to specify -d 1 when zfs list and zfs get are
called with -t snapshot on a datset. This commit extends the same
behaviour to -t bookmark.

This commit also introduces the 'snap' shorthand for snapshots from
zfs list to zfs get.
