Remove LSB support

Remove LSB support

LSB as a standard isn't current and isn't well suited to embedded
anyway. Its putting artifical constraints on the system and with modern
layer technology, would now be better off as its own layer. As such
its time to split it out.

The only part with some (marginal) usage is lsb_release,
which is split from the lsb package into an own lsb-release
package.
