Make direct calls to rb_{obj_instance,mod_module}_{eval,exec} not pass keywords

In general RB_PASS_CALLED_KEYWORDS should only be set if we are
sure the arguments passed come directly from Ruby.  For direct calls
to these C functions, we should not assume that keywords are passed.
Add static *_internal versions of these functions that
Kernel#instance_{eval,exec} and Module#{class,module}_{eval,exec}
call that set RB_PASS_CALLED_KEYWORDS.

Also, change struct.c back to calling rb_mod_module_eval, now that
the call is safe.
