very crude patch

Overview:

When MiniDLNA receives a "M-SEARCH" message an IGMP membership report message is triggered. This message follows the default route instead of being sent out on the interface MiniDLNA is listening on.

Steps to Reproduce:

1) Configure MiniDLNA to listen on an interface that does not have the default route (and no route for 224.0.0.22) and start it.

2) After MiniDLNA is running, fire up a DLNA client (e.g. VLC)

Actual Results:

The client (VLC) does not discover the MiniDLNA server (immediately)

Expected Results: 

The client (VLC) should discover the MiniDLNA server (immediately)

Build Date & Hardware:

MiniDLNA 1.2.1, FreeBSD 11.1-RELEASE

Additional Information:

"Prior to FreeBSD 7.0, if the imr_interface member is within the network range 0.0.0.0/8, it is treated as an interface index in the system interface MIB, as per the RIP Version 2 MIB Extension (RFC-1724). In versions of FreeBSD since 7.0, this behavior is no longer supported."

I think this should be fixed by this:
