Rename jw.pkg.cmds.distro.backend.BackendCmd to Backend, because it's not necessarily a command, i.e. doesn't necessarily have a run() method. It's more of a distribution abstraction of the steps needed for for a specific command, the run() method itself is implemented in jw.pkg.cmds.distro.CmdXxx.
This commit is the beginning of a bigger move to change the distribution backend class hierarchy. At the end of this change set, the backend command should not derive the backend classes from a base specific to the respective distribution, but from an abstract base class specific to the command run. The distribution specifics are then going to be encapsulated in another class called "Util", an instance of which is going to be provided to the backend as .util member.
