setlocale in ns_init_locale is only there to check if the locale is
valid, it resets it back to its initial value at the end.

There was some trouble with warning messages in the terminal when
using an invalid locale ID (see bug#51321), but that may only be
because Daniel had changed the code to set LC_ALL instead of LANG.

I preferred setting LANG anyway because it acts as a fallback, and
this is pretty much intended as a fallback, anything else explicitly
set will override it.

Out of interest, when is it slow? Is it when we have an invalid locale
ID?
