unbound: fix boot time and default run directory

Unbound struggles with boot ifup, so procd triggers changed to push
outside of this noise. Unbound has run in /var/lib/unbound/, so chroot
(jail) protects /etc/, and it can save flash wear. Compiled defaults
reflect this now, so Unbound tools are easier run on the command line.
