tests/mctp-pipe: Use SOCK_STREAM for internal serial link

Currently, we have no way to determine when the MCTP session should be
closed, when using SOCK_DGRAM. While this will be the case for a "real"
serial link, we want the test program to be able to terminate.

This change uses SOCK_STREAM instead, which means that we can terminate
the MCTP session on EOF on stdin. This allows the pipe to exit.

Additionally, this means that the read() boundaries may not correspond
to the write() boundaries, which gives more testing to the serial state
mechanism.
