Fix wrong package availability check for multi-user.

Currently we are checking if the ICS package is enabled during runtime
before we try to bind to it. However, if we switched to second user,
checking availability will always return false. Fix this by checking
it with package manager of the current user.

Test: make sure Telecom can bind to all non-UI ICS after switched to
second user manually
