Aaron Klotz d7962e3bcf ipn/ipnserver, util/winutil: update workaround for os/user.LookupId failures on Windows to reject SIDs from deleted/invalid security principals.
Our current workaround made the user check too lax, thus allowing deleted
users. This patch adds a helper function to winutil that checks that the
uid's SID represents a valid Windows security principal.

Now if `lookupUserFromID` determines that the SID is invalid, we simply
propagate the error.
