[Buildroot] [git commit] manual: get rid of the lists of packages

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=d4db4277ffbd1fae478ba748c626eddc7c220e67
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

We currently have four lists of packages in the manual:
  - the non-virtual target packages,
  - the virtual target packages,
  - the host packages,
  - the deprecated features.

Those list take more than half of the manual. They do not serve much
purpose except to show off.

After the recent discussion on the list [0], remove them all.

We can now get rid of our biggish and complex generating script (and its
companion library kconfiglib).
