[PATCH 1/2] utils.py: Check for duplication dependency entries

[Mark Hatle <mark.hatle@windriver.com>]

explode_dep_versions is not able to have duplicate entries.  Previously
duplicate entries ended up with the last item being the one returned to
the caller.

Instead we now throw a ValueType exception.  This will ensure the caller
always gets the full set of declared dependencies.
