[PATCH 4/5] revactor: remove fcntl dependency

[Eric Wong <e@80x24.org>]

In the unlikely case somebody runs revactor, they won't need to
load the extra fcntl.so library into their process anymore.

In retrospect, we could've alway used IO#close_on_exec= since
it appeared in 1.9.1 and (IIRC) revactor always required 1.9.1+
