Avoid using UserHandle.isSameApp() in package check

SDK sandbox processes created from the sandbox package do not have the
uid of the package - they use a separate uid range instead.
UserHandle.isSameApp() does not take this account when run for the
sandbox.

Instead, use the API PackageManagerService.isSameApp() that takes into
account the differences between sandbox package uid and sandbox process
uid.
