This add tests to the zapwrapper package and also adds a test
to verify the issue in https://github.com/storj/storj/issues/6006

Lazyfilewalker was failing with SIGPIPE which was quite
misleading. The command was failing because the
the value of the --lower-io-priority flag was assumed
to be an arguement since it was passed as
"--lower-io-priority true" instead "--lower-io-priority=true"

The execwrapper package wraps the exec.Cmd and has a Command
interface that mimics the behaviour of the exec.Cmd.
This is useful for testing the lazyfilewalker subprocesses
by stubbing instead of spawning a real subprocess.

As part of fixing the IO priority of filewalker related
processes such as the garbage collection and used-space
calculation, this change allows the initial used-space
calculation to run as a separate subprocess with lower
IO priority.
This can be enabled with the `--storage2.enable-lazy-filewalker`
config item. It falls back to the old behaviour when the
subprocess fails.
