Work around DragonFly BSD kernel bug
DragonFly's x86_64 assembly implementation of copyinstr() checks the
wrong pointer when deciding whether to return EFAULT or ENAMETOOLONG,
causing it to always return EFAULT for overlong paths. Work around it
by treating EFAULT the same as ENAMETOOLONG on DragonFly.
