ignore: fix path concatenation of .hgignore on Windows

Since 3de48ff62733, .hgignore is ignored on Windows because a pat may have
a drive letter, but pathutil.join is posixpath.join.

  "z:\foo\bar/z:\foo\bar\.hgignore"

Instead, this patch uses os.path.join() and util.localpath() to process both
parts as file-system paths.

Maybe we can remove os.path.join() at dirstate._ignore because 'include:' is
resolved relative to repo root? It was introduced by a04c7b74b3d5.
