Changed INTERACT_ACROSS_PROFILES appop to be set per UID

In some cases, enforceCrossUserOrProfilePermission fails for packages
which have INTERACT_ACROSS_PROFILE appop granted if it shares the uid
with another package that doesn't hold the permission,
this is because getPackagesForUid is used to get the
callingPackage which could return either packages randomly.
I've changed setting the appop to be per uid instead of per package,
