oeqa/runCmd: print stderr when that is a separate stream

runCmd by default merges stderr into stdout, and only
needs to print stdout when errors occur. When stderr
is requested as a separate stream, and an error occurs,
stderr is discarded, obscuring useful error messages.
This changes the output to include both streams.
