linaro-hwpack-replace only replace same name deb pkg but in fact it needs a smart match

If using a something old deb package to replace to a new hwpack, and the deb package name is different, the package will add to hwpack directly, so that l-m-c can't determine which package is to be installed in later hwpack installation.

e.g.
A hwpack contains a image deb named linux-image-2.6.38-1002-linaro-mx51_2.6.38-1002.3_armel.deb, now I need to replace it to a new deb linux-image-2.6.38-1003-linaro-mx51_2.6.38-1003.4~ppa6_armel.deb, after running l-h-r, new deb will add to hwpack but old deb also exists.

The right action is to delete old deb and add new deb.

We have name rule for all deb names, [deb name]_[vesion], l-h-r needs a smart match to deb name and replace the right deb package.
