copy /etc/hostid from installer root to target

/etc/hostid is used by ZFS (spl.ko) to determine which host last imported a
pool creating and importing a pool with one hostid during install and booting
with a different one (or none) leads to the system refusing to import the pool
see spl-module-parameters(5) and zpool(8).

by copying the /etc/hostid from the installer into the target system we ensure
that it stays consistent
