parameter for capture_launch_thread()

- NULL is given as parameter on function execution
- it is defined with parameter capture_info_t *capinfo
- fix for warning: a function declaration without a prototype is deprecated
in all versions of C and is treated as a zero-parameter prototype in C2x,
conflicting with a subsequent definition
