crontab(1): reduce usage()

[Jason McIntyre]

hi.

diff to reduce verbosity in crontab(1) usage. before:

$ /usr/bin/crontab -Z
crontab: unknown option -- Z
usage: crontab [-u user] file
   crontab [-e | -l | -r] [-u user]
(default operation is replace, per 1003.2)
-e  (edit user's crontab)
-l  (list user's crontab)
-r  (delete user's crontab)

after:

$ /usr/obj/usr.bin/crontab/crontab -Z
crontab: unknown option -- Z
usage: crontab [-u user] file
   crontab [-e | -l | -r] [-u user]

ok?
