Improve application launching speed

To improve app launching speed on Tizen (using launchpad), Use -fPIE option instead -fPIC and attach DALI_EXPORT_API in front of each example's main function. This is the compare result between before and after patch. (On hawkP 2.4 / using hello-dalidemo that has one pushbutton on stage) | before Patch | After Patch | --------------------------------------------- | hello-dalidemo | hello-dalidemo | --------------------------------------------- | AVG MIN MAX | AVG MIN MAX | | 1134 1060 1188 | 291 250 337 | After patch, launching speed drops to 30% of before.
