[Libguestfs] [PATCH libguestfs] build: revive the ocaml package tests

This reinstates the autogen.sh-based test for the two required ocaml packages. I've tested it by running autoconf.sh first with neither of the two packages installed, then with only ocaml-xml-light installed. In both cases, autogen.sh failed as required. When both were installed, it worked as expected.
