sd-bus: allow vtable format structure to grow in the future

We would check the size of sd_bus_vtable entries, requring one of the two known
sizes. But we should be able to extend the structure in the future, by adding
new fields, without breaking backwards compatiblity.

Incidentally, this check was what caused -EINVAL failures before, when programs
were compiled with systemd-242 and run with older libsystemd.
