trace: Fix 'char **' compilation error in simple backend

Browse Source 
Currently, the generated function body will do "strlen(arg)" but the
argument could be 'char **' or 'char * const *'. Avoid that by excluding
such cases in is_string check.

Reported by patchew's "make docker-test-mingw@fedora".
