Fix hidl_ssvc_poll thread issues
1) Patch poll wake up handling logic so that thread no longer quits
on spurious wake up.
2) Patch(simplify) thread initialization, so that it will not hang
on waiting for conditional variable.
Test: 1) send signal 3 to system_server, does not observe thread quit.
Test: 2) adb shell "stop;start" many times, every time thread starts.
