languages: Fix RTL language file generation

The 'rtl' flags for Arabic and Hebrew was inadvertantly deleted
in 7ff3c94e1 (over a year ago, in November 2020!) but it's actually been
broken since the introduction of 'updatelang', in 2305966d (July 2020)

The fix here is to change the 'RTL' flag from an <options> section in
the language file to a comment in the header.  It's not as pure in a
design sense but it makes for a much cleaner implementation.

I may further revamp this by making the 'RTL' flag into an explicit
LANG_xxx string
