Subject: [PATCH] Add yum support to kickstart.package functions

Yum only supports passing one package to check its info.
Other package managers allow you to have several packages name, and
return non-zero whenever one is not installed.

To have the same behaviour on yum, we iterate over the list until we
find one that is not installed.
