The memory-failure tests call cleanup() only after all result checks. A
failed ASSERT_* invokes fixture teardown and aborts the test, so it skips
cleanup() and leaves the injected page hardware-poisoned.
Invoke cleanup() from FIXTURE_TEARDOWN() instead. Guard it with
self->injection_attempted so tests that exit before injection do not try
to unpoison a page when no injection was attempted. Injection can poison
a page before returning an error or delivering SIGBUS, so teardown must
clean up after every injection attempt. This runs the existing HWPoison
and HardwareCorrupted checks on both normal and assertion-failure paths.
