Import kickstart module from mic

We are going to customize it so we need a local copy here.
Since it's used by the base and loop imagers we copy their code

kickstart: Use /usr/bin/echo rather than /bin/echo

Maui coreutils package has binaries on /usr/bin, /bin contains links
for now and that's cause the check not to work.
Bump version to 0.2.1
