locale.c: Use parallel array to simplify

This allows the numeric fields returned by localeconv() to have the same
logic as the string fields, simplifying the code a bit.  They weren't
previously handled the same because one category doesn't have any
numeric fields.  But this is now handled by creating an array and making
its corresponding element NULL, so the strings and numeric fields are
handled in the same way.
