openposix: Remove unreachable code.

Change all occurences of:

int main(void)
{
	...

	if (failed) {
		printf("Test FAILED\n");
		return PTS_FAIL;
	} else {
		printf("Test PASSED\n");
		return PTS_PASS;
	}

	printf("This code should not be executed\n");
	return PTS_UNRESOLVED;
}

And similar for:

int main(void)
{
	...

	if (failed) {
		printf("Test FAILED\n");
		return PTS_FAIL;
	}

	printf("Test PASSED\n");
	return PTS_PASS;
}

To remove unreachable code.
