perf: Fix static strings treated like dynamic ones
The raw_field_ptr() helper, used to retrieve the address of a field inside a trace event, treats every strings as if they were dynamic ie: having a secondary level of indirection to retrieve their contents. FIELD_IS_STRING doesn't mean FIELD_IS_DYNAMIC, we only need to compute the secondary dereference for the latter case. This fixes perf sched segfaults, bad cmdline report and may be some other bugs.
