initrdscripts: Try to boot if boot label is unknown
The init-live.sh scripts assumes that the boot label set by
the LABELS variable is either "boot", "install", or
"install-efi". If that variable is overridden to something else
we fall off the end of the case statement and the system locks
up. If the boot label is unknown, at least attempt to boot.
