dyninst: patch to build dyninst with older gcc (#10160)

* dyninst: patch to build dyninst with older gcc

Add 'v9.3.2-auto.patch'.  This patch changes some 'auto t: type' usage
to the older but equivalent 'type.begin()'.  This allows building
dyninst 9.3.2 with gcc 4.4 which doesn't support the newer syntax.
This patch is harmless with newer gcc.

* Fix typo in patch.  (My bad for sloppy cut-and-paste.)

* Restrict the patch to gcc 4.7 and earlier.  gcc 4.8 supports the newer
usage and thus doesn't need the patch.
