add vlan support

[Dimitri John Ledkov]

[Impact]

 * xenial 16.04.0 has vlan support in netcfg, however it was failing to propagate vlan settings to the installed system. This change fixes the logic to copy the settings through to the installed system correctly, when using ifupdown (the default case)

[Test Case]

 * Install system with vlan configuration, e.g. boot with netcfg/vlan_id=123
 * Make sure installed system has vlan_id configured in /etc/networking/interfaces and networking comes up as expected

[Regression Potential]

 * Medium, netcfg postinst is changed affecting all installations

[Other Info]

 * vlan_id question is of medium priority, therefore if navigating the installer interractively, one should lower the debconf priority before configuring networking.

This bug was fixed in the package netcfg - 1.135ubuntu6

---------------
netcfg (1.135ubuntu6) yakkety; urgency=medium

  * With vlan connection type, finish-install.d would decide to purge
    network configuration and writeout loopback interfaces only, due to
    the assumption that !wired, must be wireless. Write out loopback only
    config with wireless only connection type. With this change vlan
    settings propagate through to the system, after additional
    network-manager changes were added. LP: #1567687
