[patch] multimedia/libmp4v2 and OVERRIDE_DIRDEPTH

[Rumko <rumcic%gmail.com@localhost>]

OVERRIDE_DIRDEPTH is by default set to 2, but libmp4v2 has config.{guess,sub}
not only in ${WRKSRC} but also in ${WRKSRC}/common/video/iso-mpeg4/. That's
why this patch is needed (for now, only found this package that needs this so
there should be no need to change the default?).
