trace: strlen() return doesn't account for the NULL 

We need to add one to the strlen() return because of the NULL
character.  The type->name here generally comes from the kernel and I
don't think any of them come close to being MAX_TRACER_SIZE (100)
characters long so this is basically a cleanup.
