The userlist executable wastes four characters in
mangling 'ut->ut_host' into 'tty_list[#].locale'.
The wrong macro was use in testing the length.

One could also imagining raising the value of
ULIST_LOCALE in order to handle most cases of
numerical IPv6 addresses (when the UTMP client
could not resolve into a host name) without
truncating it in the printed line. Increasing
the length would change the direct correspondence
with printout by 'last', but could still be
evaluated.

Description: Use full length of field 'locale'.
 Test length of 'ut->ut_host' against the available
 space ULIST_LOCALE for best information content.
