Commit 58263ed7713e ("xen: add /buildinfo/config entry to hypervisor
filesystem") added a dependency to .config, but the hypervisor's build
config could be have another name via setting KCONFIG_CONFIG.
Fix that by using $(KCONFIG_CONFIG) instead. Additionally reference
the config file via $(XEN_ROOT) instead of a relative path.
