qom: Make "object" QemuOptsList optional

This code is going away anyway, but for a few more commits, we'll be in
a state where some binaries still use QemuOpts and others don't. If the
"object" QemuOptsList doesn't even exist, we don't have to remove (or
fail to remove, and therefore abort) a user creatable object from it.
