In general the way of solving this is not issuing a higher version of
pkgA and pkgB. In cases you do not control those packages you can add a
Conflict: pkgA and Conflict: pkgB to pkgC which issues an error if those
packages are being installed while pkgC is on the system. Adding such
Conflict:s without a version number is a bit fishy but this is needed
here to rule out all future versions that might come out during pkgC's
