Add 'zfs diff' coverage to the ZFS Test Suite

Browse Source 
This change adds four new tests to the ZTS:

 * zfs_diff_changes: verify type of changes diplayed (-, +, R and M)
 * zfs_diff_cliargs: verify command line options and arguments
 * zfs_diff_timestamp: verify 'zfs diff -t'
 * zfs_diff_types: verify type of objects (files, dirs, pipes...)
