This is a residual of the $FreeBSD$ removal.

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

Otherwise bsd.dirs.mk will create the directory with the default
package (utilities) and we end up with a bunch of empty dirs managed
by this package while it shouldn't be the case.

Most places spelled it -locales, but numericdef spelled it as -locale
in just this one place. Pluralize it.

The only exception here being C.UTF-8 as this is the default
locales so it needs to always be installed

the way SAMEDIRS was defined was an abuse of bsd.dirs.mk resulting in
all the directory to be created in one single command, but DESTDIR is
only prepend once on the first element of the list

Switch to the properway to use bsd.dirs.mk

The framework knows how to create directories and tag them properly
for a the creation of a mtree, not need to hardcode all the locales
entries in bsd.usr.mk

This simplifies addition of new locales but also allow people building
with WITHOUT_LOCALES to end up with a directory full of empty files

Unicode locales are maintained and to evolved in cldr.
Generating the other locales from the unicode gets more and more painful
over the time.

Let's freeze the other locales to cldr 34.0.
