vim: add recipe for vim-tiny

Changes:
- Add bb for vim-tiny based on vim.bb
- Change PACKAGECONFIG and do_install for vim-tiny
- Change BPN to vim in vim.bb so it works fine when required by vim-tiny
- Add proper alternative links for vim and vim-tiny to avoid conflicts
- Don't use do_install_append in vim.bb so it works fine when required by vim-tiny
