lib/Kconfig: Do not select WW_MUTEX_SLOWPATH with PROVE_LOCKING 



WW_MUTEX_SLOWPATH injects a deadlock defined with inject countdown which
have performace impacts.

Few frameworks like DRM has recovery mechanism when a deadlock is observed,
which releases all the locks and tries to re-aquire them causing delay in
displaying a frame onto the screen.
