Don't fake step for hwthread rtos. (#393)
Fake step is a hack introduced to make things work with real RTOSs that
have a concept of a current thread. The hwthread rtos always has access
to all threads, so doesn't need it.
This fixes a bug when running my MulticoreRegTest against HiFive
Unleashed where OpenOCD would return the registers of the wrong thread
after gdb stepped a hart.
