Remove darwin-only restriction on ollama (#5284)

* Remove `darwin`-only restriction on `ollama`

Hopefully resolves https://github.com/pkgxdev/pkgx/issues/975

* add -buildmode on linux

* ollama needs certs to pull from model registry

* certs needed at runtime

* add pkill for linux

* test pgrep

* pkill needs -x for exact match
