kbuild: implement CONFIG_HEADERS_INSTALL for Usermode Linux
userprogs sometimes need access to UAPI headers.
This is currently not possible for Usermode Linux, as UM is only
a pseudo architecture built on top of a regular architecture and does
not have its own UAPI.
Instead use the UAPI headers from the underlying regular architecture.
