Fix daemon crash from the Android 17 IServiceConnection change (#784)

Android 17 (API 37) reshaped the IServiceConnection callback and dropped the
old overload instead of keeping both:

    void connected(in ComponentName name, IBinder service,
                   in @nullable IBinderSession session, boolean dead);

ManagerGuard overrode only the three-argument form, so as soon as system_server
dispatched the new transaction the Stub landed on an abstract method and the
daemon died with AbstractMethodError, taking the manager session down with it.
Only the Xiaomi XSpace workaround binds this connection, which is why the crash
was reported on HyperOS first; the interface change itself ships in stock
Android 17 and is not vendor specific.

Declare both overloads in the IServiceConnection stub and override both in
ManagerGuard, so every supported release finds the method system_server
dispatches. IBinderSession is stubbed as an empty interface, since the type is
only referenced by the descriptor of the new overload.
