Autogen: Add AUTOMOC test for target dependencies forwarding

Adds an AUTOMOC test that tests if dependencies from add_dependencies()
of an ORIGIN target are forwarded to the ORIGIN_autogen target.

Also fixes the AUTOMOC test that tests if dependencies from
target_link_libraries() of an ORIGIN target are forwarded to the
ORIGIN_autogen target. The test now fails in the ORIGIN_autogen build
if SimpleLib wasn't built before.
