Always reference newly created script using full path.

Always reference newly created script using full path.

When running build/install-chroot.sh to setup a Lucid64 environment for
testing on a Ubuntu Precise box the script fails with
  sudo: lucid64: command not found

This is because in Ubuntu Precise root does not have /usr/local/bin in
the path. Most references use the full path, this changes the remaining
to do so too.
