xen: introduce CONFIG_SYSCTL

We introduce a new Kconfig CONFIG_SYSCTL, which shall only be disabled
on some dom0less systems or PV shim on x86, to reduce Xen footprint.

Making SYSCTL without prompt is transient and it will be adjusted in the final
patch. And the consequence of introducing "CONFIG_SYSCTL=y" in .config file
generated from pvshim_defconfig is transient too, which will also be adjusted
in the final patch.
