Actually remove all of SpcSpOpusInfo.

So we had SpcSpOpusInfo until c0c4da6c67, when we realized MS no longer
includes those fields in their data, and removed them.

Except it didn't remove the data from the OID table or the enum from the
list, so all the OIDs after that were off by one.

Probably this confirms that a lot of things aren't checking those
completely senseless bits of the Authenticated Attributes.  I can't
decide if that's terrifying or not.

Don't set SO_PASSCRED.

It would appear that on recent kernels, setting SO_PASSCRED means you
always get SCM_CREDENTIALS control messages back instead of what
sendmsg() sent you, and SCM_RIGHTS works just fine without it.
