Avoid mojibake in "$!"

In stress testing, I discovered that the LC_CTYPE and LC_MESSAGES
locales need to be the same locale, or strerror() can return
question marks or mojibake instead of the proper message.

This commit refactors the handling of stringifying "$!" to make the
locales of both categories the same during the stringification.

Actually, I suspect it isn't the locale, but the codeset of the locale
that needs to be the same.  I suspect that if the categories were both
in different UTF-8 locales, or both in single-byte locales, that things
would work fine.  But it's cheaper to find the locale rather than the
locale's codeset, so that is what is done.
