Switch the default locale to C.UTF-8 before FreeBSD 13

[Olivier Certner]

Hi,

Yes, please.

As an example, defaulting to C locale causes problems with certain apps when 
accessing file names containing non-ASCII characters.

Sure, old-timers may have customized their systems, and even their 
installation images, but this is impractical for temporary VMs, or newcomers.

Never had a problem while using build/install scripts in base or building 
ports with a current locale of fr_FR.UTF-8, except a minor one, unrelated to 
UTF-8, when building the doc (see https://bugs.freebsd.org/bugzilla/
show_bug.cgi?id=246936)).

Regards.
