xen/privcmd: make option visible in Kconfig

Browse Source 
This configuration option provides a misc device as an API to userspace.
Make this API usable without having to select the module as a transitive
dependency.

This also fixes an issue where localyesconfig would select
CONFIG_XEN_PRIVCMD=m because it was not visible and defaulted to
building as module.

[boris: clarified help message per Jan's suggestion]

The hypercall passthrough driver allows privileged user programs to
perform Xen hypercalls. This driver is normally required for systems
running as Dom0 to perform privileged operations, but in some
disaggregated Xen setups this driver might be needed for other
domains, too.
