Subject: vpn-connection: set the MTU for the VPN IP interface

The 9b79e6c73 commit moved setting of the MTU from IP4Config to NMDevice, but
VPN connections don't have a NMDevice instance (yet). Set the MTU also from the
VPN connection. Also, copying of the MTU to the IP4Config is no longer needed
as the ip4_config_commit no longer sets the MTU.

Fixes: 9b79e6c732ffb2fb105647c1465070d36a6cc180
