x86/kconfig/defconfig: Enable CONFIG_FHANDLE=y

systemd has a hard dependency on CONFIG_FHANDLE.
If you run systemd with CONFIG_FHANDLE=n it will somehow
boot but fail to spawn a getty or other basic services.
As systemd is now used by most x86 distributions it
makes sense to enabled this by default and save kernel
hackers a lot of value debugging time.
