sys-fs/aufs-util: mark as LTO-unsafe

It uses an elaborate macro to insert __attribute__ ((section ("EXP"), used))
as an export annotation, and then uses readelf to dump this and assemble a
linker version script. Apparently visibility attributes is too boring. ;)

It totally falls over when exposed to LTO.
