games/gog-unpack: Fix unpacking with newer bsdtar

With newer bsdtar, extraction fails because of this error:

  bsdtar: Pathname cannot be converted from UTF-8 to current locale.
  bsdtar: Archive entry has empty or unreadable filename ... skipping.
  bsdtar: Error exit delayed from previous errors.

The reason is that the current locale isn't set during Nix builds, so in
order for bsdtar to work properly, let's set it to C.UTF-8 so that it
hopefully doesn't convert anything at all (which is what we want).
