monitor: Lookup existing monitor interface via netlink
...
On startup, request a list of interfaces via netlink. Find out whether
an interface of type nlmon exists and use it if it has all the needed
flags set. The default name of the interface is 'nlmon', which can be
changed from the command line. If the interface name is in use and is
not an nlmon type, print out an error message and exit.
