make Sherlock compilable on Darwin without hacks due to missing direct IO

I define O_DIRECT flag to be 0 on Darwin, hence enabling direct IO will
have no effect.  This ignoring will be silent.  A clean solution (with
failure when enabled by the user) would be much more complicated and I just
wanna make Sherlock compilable on Darwin for desktop/debugging usage.
