mima: Add dependencies on script_latin and western_name_order.

You definitely should have script_latin once your patch includes any text in
order to make it look prettier. Yes, the language patches include it
automatically, but this still allows users to get a nice Mima patch without
being forced to pick a translation from Touhou Patch Center.

Also adding western_name_order because you certainly want that as well.
