locale.c: Add fcn to hide edge case undefined behavior
The POSIX 2008 API has an edge case in that the result of most of the
functions when called with a global (as opposed to a per-thread) locale
is undefined.
The duplocale() function is the exception which will create a per-thread
locale containing the values copied from the global one.
This commit just calls duplocale, if needed, and the caller need not
concern itself with this possibility
