[PATCH] package_ipk.bbclass: print opkg output on error

["Konrad Weihmann" <kweihmann@outlook.com>]

in case the opkg command fails in before no output of the tool
itself was printed to assist the user with debugging the issue.
Print all output of the tool by using CalledProcessError wrapper around
the call
