Support "make check" in contrib

Added a new option --extra-install to pg_regress to arrange installing
the respective contrib directory into the temporary installation.
This is currently not yet supported for Windows MSVC builds.

Updated the .gitignore files for contrib modules to ignore the
leftovers of a temp-install check run.

Changed the exit status of "make check" in a pgxs build (which still
does nothing) to 0 from 1.

Added "make check" in contrib to top-level "make check-world".
