dhcp-server, dhcpv6-server: T2432: chown lease file to nobody:nogroup

Commits f37194604 and 0cbad2850 migrated isc-dhcp-server(6) from
SysVInit to SystemD, changing the user and group dhcpd is started as.
This caused a permission error when dhcpd tried to write to lease files:

  dhcpd[2829]: Can't create new lease file: Permission denied

As dhcpd is started as nobody:nogroup, setting the permissions on the
lease files to 664 root:vyattacfg would make dhcpd unable to write to
them. We can't make the files other-writable, as that would be a big
security issue, so we need to set either the owner or group of the files
to be dhcpd writeble. There should be no harm in changing both to
nobody:nogroup, as they were previously root:root.

If some other VyOS code doesn't like the ownership of these files in
/config, they can be either excluded from the check (possibly moved into
their own directory), or changed back to root:vyattacfg and vyattacfg added
to nogroup.
