localcharset: short-circuit the search for an alias on a Mac
* lib/localcharset.c (get_charset_aliases): Add a tautological
UTF-8 entry to speed up the search for this case.
Most machines default to a UTF-8 locale nowadays, so begin the
list of aliases with a dummy UTF-8 entry so it will be found
immediately and a time-consuming search through the rest of
the list is avoided.
