There's a lot of overlap between this file and webkitpy/common/webkit_finder.py
. Can we add logic to that file instead?

nit: "find_typ_dir" reads to me that this function simply looks for something
and doesn't make any side effect.  Actually, the purpose of this function is to
update the system path.  Then, I'd recommend to rename this function to
something like "add_typ_dir_to_sys_path".

Agreed.

+    if path_to_typ not in sys.path:
+        sys.path.append(path_to_typ)

ditto

+    path_to_bindings_scripts = get_bindings_scripts_dir()
+    if path_to_bindings_scripts not in sys.path:
+        sys.path.append(path_to_bindings_scripts)
