remove kgio from all read(2) and write(2) wrappers

It's fairly easy given unicorn was designed with synchronous I/O
in mind.  The overhead of backtraces from EOFError on
readpartial should be rare given our requirement to only accept
requests from fast, reliable clients on LAN (e.g. nginx or
yet-another-horribly-named-server).
