image: always rebuild kernel loaders

Kernel loaders like the lzma-loader currently don't track changes to
their sources. This can lead to an old version of a loader to be used
when a build tree is not clean between builds.

As the loaders are tiny and the build times are insignificant, simply
force rebuilding them on every build to avoid this problem.
