serial: Don't append serial header to received packets

In change c67605bc9, we separated the serial header & tailer from the
actual MCTP packet data. However, in the RX path we still included the
header, which now consumes more than the allocated header space,
resulting in an assertion in the RX path.

This change removes the serial-specific header data from the incoming
MCTP packet.

API,core: Add reference from binding to mctp core

All of the prototype binding implementations so far have added a
reference to the core struct mctp from their binding.

This change adds a the struct mctp pointer to struct mctp_binding, so it
doesn't need to be included in every implementation.

This also allows us to drop the struct mctp * argument where we have a
reference to a binding.

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.
