Explicitly disallow multiple user execute

Explicitly disallow multiple user execution:
it's not expected because everything runs as system
but this change explicitly rules out execution.

This change also adds an xTS to confirm that
a secondary user installing the app triggers
an update (as the owner) and the device is updated
correctly.

Test: Manual testing installing updates as secondary device user
Test: PTS: run pts -m PtsTimeZoneTestCases
