Update to 4.1.11 and add buffer fix for rec_control

The changelog:

#7434: Add an option to export only responses over protobuf #7430:
Reduce systemcall usage in protobuf logging

Also add a fix (pulled in from OpenBSD) for rec_control's buffer
being too small to handle output of some commands. This could be
remedied by setting net.local.dgram.maxdgram=131072 in
/etc/sysctl.conf, but this patch omits that requirement.
