Essentially this helper function is similar to close_stream(), but for
file descriptors.
When a file descriptors are close()'d status of write is often
overlooked. The close_fd() will try to determine what happen to writes
with fsync() before closing the file descriptor.

The close_stream() is copied from GNU lib. Inspiration to do this is
talk by Jim Meyering - Goodbye World! The perils of relying on output
streams in C.
