aout support in ldconfig hasn't been required since FreeBSD 2.x.
If someone needs to use FreeBSD 2 shared libraries they will be best
served by using a FreeBSD 2 ldconfig as well.
In aa5e1b42e6 we removed the ldconfig a.out invocation from rc.d but
left the support in ldconfig itself. Remove it now.
