[PATCH 4/4] maint.mk: Imporved LINGUAS generation.

[Martin von Gagern]

This change avoids duplicates for address@hidden and address@hidden  It also 
ensures
that the list is completely sorted and that any comment lines preceding the
list of linguas will be preserved.  Non-lingua lines following the list of
linguas will be moved in front of the linguas, so it is suggested to avoid
any such lines.  A header should be enough.
