shill: vpn: Add support for creating a tunnel interface

Use the ioctl inteface for creating a TUN device (no RTNL interface
for this appears available).  Also create a means for removing
interfaces, using the RTNL interface.

BUG=chromium-os:26841
TEST=New unit test for RTNL interface, manual testing for ioctl
interface and for TUN interface detection and handling.
