fix go bindings

This PR fixes missing ggml issues in go bindings

[gleicon]

Not sure how to do it but there are a couple of lines missing on my Mac M1 + Go setup at the Makefile to add include files Go will need:

$ diff -a Makefile ~/tmp/Makefile_new_whisper

I tried this fix but sadly it didn't work for me 😕

I believe this pr has been superseded by 206459a.
Please feel free to reopen if there is anything missing in the current implementation
