Use ASSERT_EQ() instead of EXPECT_EQ() to prevent segfaults after
failed API calls.
Do not run setfscreatecon_IsPerThread unless we're in permissive mode
as it will not pass otherwise.

Ueventd may take advantage of this in the future, so this CL
introduces tests that ensure that this functionality remains
consistent.
