pinky,users,who: optimize read_utmp invocation

Browse Source 
When we are only interested in entries of type USER_PROCESS, tell
read_utmp that it does not need to determine the boot time.

* src/pinky.c (short_pinky): Pass option READ_UTMP_USER_PROCESS.
* src/users.c (users): Likewise.
* src/who.c (who): Likewise, if calling list_entries_who.
