/platform/frameworks/base: Fix Airplane Mode on/off issue

Issue: Unable to turn off Airplane mode from power button
       after phone reboot

Fix: Initialize mHasTelephony before the PhoneStateLister
     is attached to the TelephonyManager so that correct
     value of mHasTelephony is reflected in the Listener.
