Setup proper sysctl(2) arguments in order to retrieve the executable
name.
Use an intermediate buffer beacause if it is too short, the sysctl(2)
call will return error. With this intermediate buffer populate the outer
one.
Note issue with too long file names on NetBSD-8(beta), this is caused by
the current implementation of vnode to path translator in the kernel. It
does not cache longer file names than 31 character ones.
