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.

platform/interfaces/health/2.0/default/healthd_common.cpp wants to use
timerfd_create() to register a wakealarm.
To use the timerfd_create() syscall with CLOCK_BOOTTIME_ALARM,
CAP_WAKE_ALARM is needed.
Since the .rc file for android.hardware.health@2.0 is shipped here in
system/core, update it here.

healthd_common.cpp uses health@2.0 for health@2.0-service
and healthd.
charger and recovery will be fixed in a follow up change.
(They still use libbatterymonitor for now).
Test: adb logcat -e "health@2.0"
Test: adb shell lshal --debug
