fixed signal-cli-native build

* due to different glibc versions, it is not possible to use the
  existing (prebuilt) libsignal_jni.so that get's shipped with the
  signal-cli binary distribution for the signal-cli native image build.
  So in order to make that work (again), we need to use our own
  libsignal_jni.so for the x86_64 build.

see #412
