www-apps/gitea: Do some house-keeping

- Drop all example ini modifications. We need to maintain them downstream
  and if they really don't work than either upstream's documentation
  should be fixed - or ours.
  This was mostly already done in the in-tree ebuild.
- Re-order and re-format IUS, blocks and eclasses.
- Drop the upgrade notice for 0.15.x as I assume the time delta is enough.
