pg_dumpall: Fix handling of incompatible options.

Browse source 
This commit teaches pg_dumpall to fail when both --clean and
--data-only are specified.  Previously, it passed the options
through to pg_dump, which would fail after pg_dumpall had already
started producing output.  Like recent commits b2898baaf7 and
7c8280eeb5, no back-patch.
