Fix bugs for installing docker, bug #1237581.
  -The change in install_docker.sh corrects a typo ('=' should be '-').
   This typo resutls in 'unable to locate the packet' error when executing apt-get.

  -The second change is in hypervisor-docker fix the error for reporting
   docker is not installed when docker is actually set up. The original line
   missed the version part of the package name.
