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.
