Set missing mask flags for kdb5_util operations

Set missing mask flags for kdb5_util operations

Set KADM5_TL_DATA for the use_mkey and update_princ_encryption
commands.  (Commit c877f13c8985d820583b0d7ac1bb4c5dc36e677e did this
for the add_new_mkey and purge_mkeys commands.)  Set appropriate flags
for the add_random_key command.

[ghudson@mit.edu: combined two commits; pruned out proposed mask flag
additions for values represented within key data or tl-data (like
KADM5_MKVNO), as those flags are currently only used in the kadm5
protocol, not to communicate with the KDB module]
