After running make, the licenses for the generated go files is updated,
resulting in a diff in the repository. This makes later invocations of
`make container` generate tags with `$ARCH-$SHA-dirty` rather than just
`$ARM-$SHA`, which causes `make manifest` to fail, as some of the
images cannot be found.
A more permanent fix would be to ensure that running `make container`
does not cause the go code to unnecessarily regenerated, but this will
at least fix CI until next year.
