health: Add CAP_BLOCK_SUSPEND

Add CAP_BLOCK_SUSPEND to android.hardware.health@2.0 service so
that when epoll_wait() is waiting on uevents and timer_fd events
it can block suspend to take the necessary action. Without this
permission, eventpoll is going to ignore the flags EPOLLWAKEUP
used in health HAL or healthloop.
