libtracefs: Add tracefs_event_enable/disable() API
Add the API of the following functions:
tracefs_event_enable()
tracefs_event_disable()
That takes a system string and an event string and enables the events that
match. Where a NULL system means (all systems) and a NULL event means all
events in the system.
