postgresql: make PGXS usable for cross-building extensions

Extensions built with PGXS need pg_config and Makefile.global, but
pg_config is a target binary and the staged Makefile.global has its
paths stripped.

Stage a shell pg_config in crossscripts and fix up the staged PGXS
makefiles so extensions can be built against the sysroot.
