pgsql: Remove superfluous tqual.h includes.

Remove superfluous tqual.h includes.

Most of these had been obsoleted by 568d4138c / the SnapshotNow
removal.

This is is preparation for moving most of tqual.[ch] into either
snapmgr.h or heapam.h, which in turn is in preparation for pluggable
table AMs.
