tracing/events: add missing type info of dynamic arrays

The format file doesn't contain enough information for
__dynamic_array/__string. The type name is missing.

Before:
# cat format:
name: irq_handler_entry
...
field:__data_loc name; offset:16; size:2;

After:
# cat format:
name: irq_handler_entry
...
field:__data_loc char[] name; offset:16; size:2;
