[PATCH net 5/5] selftests: mptcp: connect: print pcap prefix

["Matthieu Baerts (NGI0)" <matttbe@kernel.org>]

To be able to find which capture files have been produced after several
runs.

This prefix was not printed anywhere before.

While at it, always use the same prefix by taking info from ns1, instead
of "$connector_ns", which is sometimes ns1, sometimes ns2 in the
subtests.
