KERNEL_INSTALL_CONF_ROOT overrides kernel-install config lookup. When it
was set and cmdline was absent, 60-ukify still fell back to
/proc/cmdline and embedded host boot options into the target UKI.
Return an empty base cmdline in that case, matching the adjacent
90-loaderentry behavior of not searching outside the override root.
Reproducer:
KERNEL_INSTALL_CONF_ROOT=$(mktemp -d) python3 -c '
import runpy
ns = runpy.run_path("src/kernel-install/60-ukify.install.in",
run_name="not_main")
print(ns["kernel_cmdline_base"]())'
Before:
The host /proc/cmdline was returned.
