[Systeminfo] Added handling Storage for TV profile in Systeminfo

[Systeminfo] Added handling Storage for TV profile in Systeminfo

[Feature] Added two implementations of signal handling. Active one could be switched by define.
  1. was based on implementation from tizen_2.4_tv_product_migration branch
  2. was based on web wiki: https://wiki.tizen.org/wiki/System:Deviced#Usb_host specification

  On binary: 20160107.4, implementation based on Usb_host interface is correct and was tested and works correctly.
  Implementation 1 (based on tizen_2.4_tv_product_migration) seems to work in case of gathering storages also.
