[PM] Use callingUid instead of binder#getCallingUid for uninstall

When the system checks whether the caller can uninstall an app
silently, we should use callingUid to instead of the callingUid from
the Binder. Because the archive caller calls uninstall method in the
handler of PackageManagerService. The callingUid from the Binder is
system server at this time.
