utils/checkpackagelib: exclude four files from Config.in indentation check

package/Config.in, package/Config.in.host, package/x11r7/Config.in and
package/kodi/Config.in do not comply with the normal Config.in
indentation rules. However, this violation of the rule is legitimate, so
let's skip them in check-package for this specific indentation check.

This removes the last 2197 remaining warnings on Config.in files.

          fix flake8 warnings, add package/Config.* to the list]
