Support secondary user for PackageManagerShellCommandMultiUserTest#testPackageFullyRemovedBroadcastAfterUninstall

- The test can run under non-user 0 env (auto) and it will fail
  as the primary user broadcast is using the current user context.
- Change it so that all broadcast request uses per user contex so
  that it can work for test running for user 0 and non-user 0.

Bug: 234014686
Test: atest android.content.pm.cts.PackageManagerShellCommandMultiUserTest
 for phone, secondary user should be created and switched into secondary user
 to reproduce the broadcast issue.
