[PATCH v2 4/4] trace-cmd reset: Add bash tab completion for -B and -k

Implement the placeholder for tab completion of "trace-cmd reset".

Apparently trace-cmd.bash already has support for instance buffers
lookup (which is show_instances()). Employ it for -B option.

Regarding -k option, show the list of dynamic event types to ease
trace-cmd user's job.
