Fix for globbing on IBM i

- Evidently, relative paths without prefixes can cause errors with globbing on
  IBM i series. As such, using `__DIR__` helps eliminate ambiguity on those
  systems.
Prefix config glob path

- If the default glob path is detected in the set of glob paths, prefix
  it with the value of `getcwd()` prior to passing it off to the
  application. This ensures the ConfigListener will be able to glob all
  paths correctly.
