Remove support for hdf.loadpaths search paths for includes and option…

…al includes

Summary: None of our configs define `hdf.loadpaths` (in fact all of them seem to use absolute paths, though when no `loadpaths` is defined relative paths are just relative to the current config). Additionally none of our configs use the optional include (`-include`) syntax.
