(#22529) Handle no package message for different dpkg-query versions

dpkg-query changes it's notification of missing package between versions
1.15 and 1.16.  We were testing for the earlier variant 'No packages
found matching'.  This change also handles the later variant of
'dpkg-query: no packages found matching'.

Also, sigh.
