Forward-port the app bundle signing from the 4.0 branch

For now, use the same quick hack as in the 4.0 branch: Just sign the
app bundle as a while, not individual dylibs. Should factor out the
code in Makefile.in that signs all dylibs. Make sure to sign the
application app bundle only, not the SDK.
