sort: with --debug, flag setlocale() failures on OpenBSD

Locale categories are not equivalent on OpenBSD,
and LC_COLLATE only supports "C" for example.
Now LC_ALL is supported to set multiple other categories
on OpenBSD, so setlocale(LC_ALL, "") returns a string
indicating which categories were updated and which ignored.
Therefore...

* src/sort.c (main): ...Call setlocale(LC_COLLATE, "")
to explicitly check whether a specified LC_ALL or
LC_COLLATE environment variable value is supported
for the LC_COLLATE category.  Also use !! to explicitly
convert to bool to support c89 systems where bool is an int,
and thus would get values > 1.
