Configure bash environment for NGZ root. (oxidecomputer#4712)

This removes the special case for the switch zone and deploys a
consistent profile and bashrc to all non-global zones.

While understanding this is subjective, improvements here are:
* A switch zone prompt includes the local switch number (0/1) if it can
be determined;
* PATH is configured to include additional directories useful within the
zone;
* The hostname part of the prompt is truncated in zones which have UUIDs
as part of their name;
 * Coloured prompt, as per the GZ.

Pretty much everyone has their own preferred prompt format, so consensus
is unlikely here, but this is a step forward in having consistency and a
better PATH. In the limit, nobody will be logging into these zones
outside of a development environment anyway.
