This patch contains the aforementioned optimization: Call
setlocale_null_unlocked instead of setlocale_null when we know
that it's safe.

localename-unsafe: Optimize.
* lib/localename-unsafe.c (gl_locale_name_posix_unsafe): Call
setlocale_null_unlocked instead of setlocale_null.
* modules/localename-unsafe (Depends-on): Add setlocale-null-unlocked.
