test: Simpler termination handling for UDP tests
Because UDP is connectionless we don't have an in-built end-of-stream signal for our connectivity tests. We work around this by explicitly adding an end marker to our sample data and killing the listening end once it is seen. However, socat has some built-in options - null-eof and shut-null - which can be used to signal the end of stream with a zero-length UDP packet. Use these to simplify how the UDP tests are implemented. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
