/**
* Like {@link #checkSignatures(String, String)}, but takes UIDs of

* when doing the check in an IPC, where the UID is the only identity

* associated with the UIDs and checking their signatures.

* @param pkg1 First UID whose signature will be compared.
* @param pkg2 Second UID whose signature will be compared.
* @return Returns an integer indicating whether there is a matching
* signature: the value is >= 0 if there is a match (or neither package
* is signed), or < 0 if there is not a match. The match result can be
* further distinguished with the success (>= 0) constants
