I think we can rely on __NR_gettid being universally available,
we already do in other tests.

I suppose we could have a macro, e.g. PIDNS_TEST_INIT, defined this way:

#ifdef PIDNS_TRANSLATION
# define PIDNS_TEST_INIT pidns_test_init()
#else
# define PIDNS_TEST_INIT do {} while (0)
#endif

This would allow a more simple usage:

	PIDNS_TEST_INIT;
