CityHash updated to v1.1

[SuperioOne]

This PR updates CityHash to v1.1 commit. The results are looking fairly similar to the older version.

Side notes:

• CityHash32 doesn't support seed value in v1.1 code. As alternatives, there are versions that support seeds, like modified CityHash v1.1.1 from SMHasher3. However, I stick with Google's original repo and simply removed the bad seed test for CityHash32 (0x2eb38c9f).
• Added CityCrc256 test. It also doesn't support seed value.

I pushed the changes for city32.

Also, added back the known bad seed, and BadSeeds test is working as expected.
