[PATCH] osmo-gsm-tester[master]: pcap recorder: filter out SSH

[Neels Hofmeyr]

Review at  https://gerrit.osmocom.org/2595

pcap recorder: filter out SSH

The dump so far includes SSH to sysmoBTS, with binaries sent and log output
read, making the dump like 20 Mb in size for no reason; filter this out by
tcpdump expression.

Compose the expression in gen_filter() by joining a list of expressions with
'and'.
