Add a gtk testcase to provide something with complex interactions

The pkg-config testsuite has pretty good coverage of the implementation,
but it lacks a complex case that tests the interactions of non-trivial
.pc files. gtk is a very common package that meets this goal. This is a
snapshot from my F16 system, and it should provide a good way to see how
changes in the implementation regress a real world case.
