android: Make ChildExitObserver observe CrashHandlerHost

This change causes a CrashHandlerHost to be instantiated, but
ChildExitObserver won't receive child crash signals until
CrashHandlerHost begins monitoring child processes.

Also fixes compilation of crash_handler_host_linux.* on Android by
not compiling breakpad::CrashHandlerHostLinux, which was never used on

Bug: crashpad:30
