Subject: [PATCH] bpf translator: catch runtime_errors

Some simple test cases can run up against bpf-translate limitations.
Those that are signalled with a runtime_error exception need to be
caught at least in translate_bpf_pass() and a message improvised, so
that there is something more to go on than an anonymous pass-4
failure.
