capnp does not handle fd passing correctly in all circumstances. we hit such cirumstances when passing large closures path lists to build-hook. since capnp seems to ignore fds passed in non-final segments of any rpc message we just ensure that the capability including the log fd will be small enough to not be fragmented on the receiving side of the channel. cf https://github.com/capnproto/capnproto/issues/2359 Change-Id: Id22309264936b3a57bcc68a0753c3bfb3c9a43d2
