[Systeminfo] T-e-c buildbreak on mobile profile

This commit fixes buildbreak for mobile profile when using this configuration:
  gbs build -A armv7l --define="profile mobile" -R \
    http://download.tizen.org/snapshots/tizen/mobile/latest/repos/arm/packages/

Build configuration will include system_info_sim class for profiles - ivi and mobile.
System_info_sim will be excluded in common profile according to current
implementation of system_info_sim_ivi.cc and structure of SysSimInfo class.

BUG=XWALK-2861
Following patches below and conversation. 'system_info_sim.h' will be included only for TIZEN_IVI and TIZEN_MOBILE so I am ignoring this comment on purpose.
