SWDEV-275232: Replaced the use of on_exit()

on_exit() registered exit_handler function, but in the case of OpenMP applications the registered exit func exit_handler was called after the dlclose of the library. So we removed exit_handler from roctracer as it is already handled in both rocprofiler and rocprof script.
