tracepoints: move trace_print_flags definitions to tracepoint-defs.h
The following patch will need to declare array of struct
trace_print_flags in a header. To prevent this header from pulling in
all of RCU through trace_events.h, move the struct
trace_print_flags{_64} definitions to the new lightweight
tracepoint-defs.h header.
