Implement a quick and dirty hack to make sure that do_build.sh -ffu works as desired because the packages will be nuked when nanobsd.sh is run without `-n -w'.

Mute the add_port noise and add something a bit more meaningful instead if make package-name fails.

Use make in this one spot so it doesn't inject -DNO_CLEAN if and when -n is specified on the CLI to nanobsd.sh ;).

Use NANO_PMAKE and more consistent design patterns without going overboard and rototilling things unnecessarily.

Readd telnet for debugging purposes.

Add an easy knob for adding/removing additional directories not iterated over via buildworld/installworld (NANO_LOCAL_DIRS).

Please use do_build.sh -f -- -k after changing this feature to rerun buildworld and installworld.

Where did my /var/db/pkg go... >.<?

Print out what we're running add_port against so if something
fails when running make package-name, etc.. it's easy to
identify what the culprit is without having to do do_build.sh
with set -x.

We autogenerate sshd_config from ix-sshd, so there's no reason why we need to generate it in nanobsd.

Add knobs for building more legitimate debug images.
