Hashes for all pathlib.Path objects are identical

[maggelus]

When hashing a pathlib.Path object, they all have the same hash value, regardless of the actual path.

To Reproduce
a = Path('testdir')
b = Path('testdir2')
a_hash = DeepHash(a)[a]
b_hash = DeepHash(b)[b]
assert a_hash != b_hash

Expected behavior
Hashes for different Paths should be different.
