Use libsigchain on Android #1745

  1. Use libsigchain on Android

    Install page guard signal handler using AddSpecialSignalHandlerFn from
    the libsigchain in the Android runtime. This prevents traced
    applications from replacing our signal handler when they try to install
    thier own signal handlers with sigaction.
    
    This is implicitly enabled when using page_guard on Android and falls
    back to sigaction if libsigchain isn't found or the add call fails.
    
    If the signal handler watcher is enabled, the watcher thread will exit
    as soon as our handler is successfully added with libsigchain.
