Make sysctl pass the pos pointer around properly.

Nobody ever fixed the big FIXME in sysctl - but we really need
to pass around the proper "loff_t *" to all the sysctl functions
if we want them to be well-behaved wrt the file pointer position.

This is all preparation for making direct f_pos accesses go
away.
