Feature #9328: [PATCH] avoid redundant F_GETFD when O_CLOEXEC works

----------------------------------------
It is pointless to check if O_CLOEXEC works after every single
open() call.  If the kernel supports O_CLOEXEC for one open(), it is
supported for every open() syscall.

I mainly made this to make my strace less noisy.  Also similar changes to socket/socketpair/fstat planned.
