Subject: [PATCH] template: make busybox template compatible with

 core-image-minimal

The busybox template makes a lot of assumptions about how the busybox
binary found on the host was configured. Building core-image-minimal
"out of the box" does not configure busybox's 'passwd' or 'init'
applets so we need to work around this.

Chances are if you attempt to use the busybox template with a host
which is note core-image-minimal it will fail but we are making these
changes here to at least have the template work with
core-image-minimal to be able to demonstrate that it can work as well
as to have it available for the ptests.
