test/fix: OSX Test Repair (#1843)

* test with gguf instead of ggml. Updates testPrompt to match? Adds debugging line to Dockerfile that I've found helpful recently.

* fix testPrompt slightly

* Sad Experiment: Test GH runner without metal?

* break apart CGO_LDFLAGS

* switch runner

* upstream llama.cpp disables Metal on Github CI!

* missed a dir from clean-tests

* CGO_LDFLAGS

* tmate failure + NO_ACCELERATE

* whisper.cpp has a metal fix

* do the exact opposite of the name of this branch, but keep it around for unrelated fixes?

* add back newlines

* add tmate to linux for testing

* update fixtures

* timeout for tmate
