Fix dumping of casts and transforms using built-in functions

Browse Source 
In pg_dump.c dumpCast() and dumpTransform(), we would happily ignore the
cast or transform if it happened to use a built-in function because we
weren't including the information about built-in functions when querying
pg_proc from getFuncs().

Modify the query in getFuncs() to also gather information about
functions which are used by user-defined casts and transforms (where
"user-defined" means "has an OID >= FirstNormalObjectId").  This also
adds to the TAP regression tests for 9.6 and master to cover these
types of objects.

Back-patch all the way for casts, back to 9.5 for transforms.
