unistd-safer: allow preservation of cloexec status via flag

If cloexec is in use, allow the ability to preserve cloexec
flag across *_safer functions.

* lib/unistd-safer.h (dup_safer_flag, fd_safer_flag): New
prototypes.
* lib/dup-safer.c (dup_safer_flag): New function.
* lib/fd-safer.c (fd_safer_flag): Likewise.
* modules/cloexec (configure.ac): Set witness.
