Subject: busybox: Enhance to add dynamic per-file provides

When using the RPM package backend, we need a full list of per-file
provides (and requires).  The busybox package provides a number of
command line utilities, such as /usr/bin/env.  However, because
the utilities are created at post install time via scripting the
provide of each of the links was never made.  So any programs,
such as python, that require /usr/bin/env were unable to resolve
the dependency and failed.

This change only affects packaging backends that use per-file
dependency data.  Currently RPM is the only packaging backend
with this ability.
