Subject: setup: Fix removal of "." components in normalize_path
Upstream: Submitted (2015-02-03)

The code was broken in 3 ways:
* I forgot to escape the "." so it would match any character.
* The g flag is not enough to catch consecutive "." components,
  because pattern matches can't overlap.
* A trailing "." component would not be removed.

This fixes commit 3fd706a50b7dbb4f8db6e5db014729db51e6beb0
("setup: Let normalize_path deal with "."".)
