GH-106330: Fix matching of empty path in pathlib.PurePath.match() (GH-106331)

Browse source 
We match paths using the `_lines` attribute, which is derived from the
path's string representation. The bug arises because an empty path's string
representation is `'.'` (not `''`), which is matched by the `'*'` wildcard.
