platform/x86_64: Add aliases for Glados/Kunimitsu devices to generic platform

All of these devices are slated to be migrated to unibuild via
go/unibuild-migration.  Do the mosys "pre-work" for all of them at
once (that is, adding platform names for the previously used names so
we don't break anyone who depends on these names).

This is an exception to the rule "don't add new names to this list",
as these are in fact old names that existed pre-generic platform.
