tar: Update to 1.30 (V3)

For details see:

Since new 'tar' has changes in commandline option parsing,
it was necessary to adjust 'lfs/Config, 'lfs/cdrom' and
'lfs/core-updates' (thanks to Marcel for diffs and Michael for
corrections).

I have tried to make only the most necessary changes.

As always, please check.

Best,
Matthias
