lava-expect: Rename to expect-lava

To sort together (in directory listings, etc.) with the original expect/
directory and recently added expect-post/ directory. That will make
relationship between them clearer and hopefully will help avoid
mistakes/omissions (e.g., any change done to expect/ should have a
corresponding change in expect-lava/ or expect-post/, and all 3
dirs will be right on the eyes / at the fingertips to make that
hard to forget).
