security/aide06: Fix regression caused by bison 2.6.x

Bison 2.6.x+ handles the yydebug functionality differently by predefining
YYDEBUG.  The yacc logic is not expecting YYDEBUG to be defined without
an value, so it breaks on an "#if YYDEBUG" macro in a few places.

In order to make this work with pre-2.6 bison as well as current versions,
hard code the inclusion of debug symbols.  It doesn't hurt anything and
it fixes the package.
