tracing: Restore the const qualifier for field names and types definition
Restore the const qualifier in field's name and type parameters of
trace_define_field that was lost while solving a conflict.
Fields names and types are defined as builtin constant strings in
static TRACE_EVENTs. But kprobes allocates these dynamically.
That said, we still want to always pass these strings as const char *
in trace_define_fields() to avoid any further accidental writes on
the pointed strings.
