[RFC lockdep 1/4] lockdep/selftest: Make HARDIRQ context threaded

[Boqun Feng]

Since we now use spinlock_t instead of raw_spinlock_t in lockdep self
tests, we should make the emulated HARDIRQ context threaded, otherwise,
spinlock_t cannot be used in the HARDIRQ context and some test cases
will fail because of wait context checking when
PROVE_RAW_LOCK_NESTING=y.
