Subject: [PATCH] mkarchroot: stop adding C.UTF-8 to locale.gen

Adding such an entry is problematic as it results in locale -a showing:

  C
  C.UTF-8
  C.utf8
  POSIX
  (other locales)

In the above, C.UTF-8 is built-in whereas C.utf8 comes from locale.gen.

The duplicate locale has the potential to expose undesired behavior in
