netconsole: selftest: Add test for fragmented messages
Add a new selftest to verify netconsole's handling of messages that
exceed the packet size limit and require fragmentation. The test sends
messages with varying sizes and userdata, validating that:
1. Large messages are correctly fragmented and reassembled
2. Userdata fields are properly preserved across fragments
3. Messages work correctly with and without kernel release version
appending
The test creates a networking environment using netdevsim, sends
messages through /dev/kmsg, and verifies the received fragments maintain
message integrity.
