Bugfixes for pe_print_debugdata()
Use a separate iteration variable for inner loop (:blush:). This
generally prevented any debug directory entries after a
IMAGE_DEBUG_TYPE_CODEVIEW entry from being reported.
Don't leak the memory allocated for the section containing the debug
directory.

* peXXigen.c (pe_print_debugdata): Fix the iteration variable for
inner loop. Fix a memory leak.
