bug#12881: Assume at least POSIX.1-1988 for fcntl.h

[Paul Eggert]

Come to think of it, there's one more simplification:
remove the test for <fcntl.h> and the use of HAVE_FCNTL_H.
This should be safe since several modules already include <fcntl.h>
unconditionally.  Here's a patch, and I'll attach
a combined patch relative to trunk bzr 110908.
