fix(ollama): fix macOS segfault and exclude mlx/rocm/jetpack variants

- pkg_link called webi_link which called pkg_link — infinite recursion
  causing SIGSEGV on macOS; fixed by switching to WEBI_SINGLE-style paths
  so the template's webi_link handles symlinking directly
- macOS pkg_src now points to the flat ollama binary (not ./bin/ollama)
- mlx, rocm, jetpack5, jetpack6 tagged as variants so generic installs
  get the standard build instead of a GPU-specific one
