In commit da556d7 (store the value of 'camera_dir'), a memory leak
was introduced due to not freeing this memory in context_destroy().
I followed the advice in PR #639 to correct this.
Valgrind was used to find this leak and test for successful fixing.
Config included a 'camera_dir' with two camera config files.
Command ran: valgrind --leak-check=full ./bin/motion -n
