kiss: give build scripts some environment variables

- Defines DESTDIR so you no longer need to export it yourself.
- Defines CC and CXX so all builds will now work with other
  compilers if gcc/g++ are the default when unset.
- Defines KISS_ROOT with the sanitized version used by the package
  manager. It can now be safely joined with other paths.
  ("$KISS_ROOT/path/to/file")
