pg_query 2.0.2 apparently has working ARM support.
This change also re-locks sqlint to use the newer version, and
generalises the platform spec to avoid being unnecessarily
restrictive.
As before, other packages which refer to pg_query are unaffected,
because they pin an older version of pg_query which is handled
separately in the gem-config expressions.
