Warner Losh 4300e05361 build: Include sys/cdefs.h in our fcntl.h shim
On Linux with musl, sys/cdefs.h isn't included with fcntl.h, so when we
use __BEGIN_DECL and __END_DECL in this file, it fails. There's no harm
in unconditionally including sys/cdefs.h here, so do that to avoid
encoding exactly where it is or isn't needed so we don't have to know
too much about the internal state of other libc implementations.
