Add dumpcap options to set the name and description for a capture source.

Add --ifname and --ifdescr to allow the name and description for an
interface or pipe to be set; this overrides the specified name or
reported description for an interface, and overrides the pipe path name
and provides a description for a pipe.

Provide those arguments when capturing from an extcap program.

This is mainly for extcaps, so you have something more meaningful than
some random path name as the interface name and something descriptive
for the description.
