Replaced test image to fix xfail

[radarhere]

Fixes an xfail.

Pillow/Tests/test_decompression_bomb.py

Lines 54 to 58 in 18e1005

	@pytest.mark.xfail(reason="different exception")
	def test_exception_ico(self):
	with pytest.raises(Image.DecompressionBombError):
	with Image.open("Tests/images/decompression_bomb.ico"):
	pass

I've recreated the test image by hex-editting a copy of Tests/images/black_and_white.ico

The xfail was added in #5377
