Disable multi-user check for entitlement provisioning

This commit updates the logic for launching the entitlement UI
for tethering when there are multiple users. It disables the
check for whether the current user can change tethering settings
for secondary users due to a potential issue with calling
createContextAsUser. This reverts the behavior change introduced
in aosp/3289821.

One expected outcome is this change will break tethering with
entilement check enabled for HSUM-enabled devices. Since there
is no currently HSUM-enabled projects, disable this check is
safe.

Test: Manual
  1. Mock requires entitlement
  2. adb shell cmd user set-system-user-mode-emulation headless
  3. enable hotspot
