pkg-utils: qstrip MESSAGE

Currently, the MESSAGE macro double-quotes the message. But a few call
sites also double-quote the message, resulting in a borked call to echo,
like:
    $(call MESSAGE,"user text")
would expand to:
    echo "Leading text "user message" trailign text"

Just use qstrip on the user message, so we get protected from either a
comma in the user text (so make does not interpret it), or a semi-colon
(so the shell does not interpret it.)
