Speed up tests
Speed up tests

Switched the max keys test to write int64 of the same value so RLE
would kick in and the file size will be smaller (84MB vs 3.8MB).

Removed the chunking test which was skipped because the code will
not downsize a block into smaller chunks now.

Skip MaxKeys tests in various environments because it needs to
write too much data to run reliably.
