This can be run when installed or uninstalled. When uninstalled, it
requires G_TEST_BUILDDIR and G_TEST_SRCDIR to be set.
The idea with this test harness is to test the gdbus-codegen utility, its
handling of command line arguments, its exit statuses, and its handling of
various C source codes. In future we could split out tests for the core
parsing and generation code of gdbus-codegen into separate unit tests, and
just test command line behaviour in this integration test.
