Debug fallback for an unknown MAC (opt in via BOOTAPI_UNKNOWN_MAC_FALLBACK=shell).
Drops to an interactive iPXE shell instead of booting anything, so an operator
racking a new box can inspect ${net0/mac} and register it in NetBox. Not the
default because it halts the boot and is unsafe for an accidental PXE of a prod
host.
