[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 systeminfo plugin for profiles - ivi and mobile.
Systeminfo will be excluded in common profile according to current
implementation of system_info_sim_ivi.cc and structure of SysSimInfo class.

BUG=XWALK-2861
Reviewed once again. 

'system_info_sim.cc' is compiled for common and ivi.

1) compile it only for ivi (as I done but without exluding desktop build whic his misstake)
2) merge ''system_info_sim_ivi.cc' into 'system_info_sim.cc' adn build for comman and ivi
