command_ut: test: Move test into lib

This test doesn't belong at the top level. Move it into the lib/
directory, since that is where compression is implemented.

Rename it to just 'command', since it is obviously a unit test and the
_ut suffix does not add much except to make it different from the names
of other test files.
