    Debian: Backup and Restore fixes for home dir

    On Debian /home is a symlink to /var/home

    The following items are now fixed on Debian:
     - disk usage of /home would have always returned zero.
     - The backup of the /home directory would have only
    included a symlink, and none of the contents.
     - The restore would have failed due to not finding a
    valid /home subdirectory from a Debian backup.
     - The restore can now detect /var/home and extract it
    if it exists, otherwise extracting /home (ie: CentOS)

    Test Plan:
     PASS: Backup(Centos) / Restore(CentOS)
     PASS: Backup(Debian) / Restore(Debian)
