Fix upgrade path for Core to SCALE (#512)

TrueNAS Core installs by default do not have a /home directory and
so it should be omitted when copying data to new boot environment
on that platform. No attempt is made to copy a non-default /home
configuration because that directory is used in SCALE and may cause
undesired behavior post-upgrade.
