    tests: Use g_test_build_filename() instead of g_test_get_filename()
    
    Running 'make distcheck', the test expects the mock file to be installed
    under the following dir:
    
    libgovirt-0.3.4/_build/sub/tests/mock-xml-data/
    
    But as it is shipped with the tarball and is found in:
    
    libgovirt-0.3.4/tests/mock-xml-data/test-parse-vm-host-cluster.xml
    
    To fix this problem, we pass 'srcdir' to the test and use it with
    g_test_build_filename() instead of g_test_get_filename(), because it
    requires environment variables G_TEST_SRCDIR and G_TEST_BUILDDIR to be
    set by glib-tap.mk and related files, bringing some extra complexity to
    the build system.
