android.java : re-add ggml source updates (#2975)

This commit updates the ggml source to include the new unary and binary
operations. I merged https://github.com/ggerganov/whisper.cpp/pull/2958
which seems to have overwritten the changes to the ggml source which
were added in https://github.com/ggerganov/whisper.cpp/pull/2972.

Sorry about this.
