Print the unchunked_ext_msg bit in get_source_cap

A new bit was added to the Source Fixed Supply PDO in PD 3.0, saying
whether the source supports unchunked extended messages.  It's not
really relevant to the PD Buddy Sink since it itself doesn't support
them, but users might want to know and it's very little work to print
it, so now it does.
