llm: do not evaluate symlink for exe path lookup (ollama#9088)

In some cases, the directories in the executable path read by
filepath.EvalSymlinks are not accessible, resulting in permission
errors which results in an error when running models. It also
doesn't work well on long paths on windows, also resulting in
errors. This change removes filepath.EvalSymlinks when accessing
os.Executable() altogether
