If we need to ignore more packages, we can use the --ignore multiple times.

go-licenses check ./... \
    --ignore github.com/xi2/xz,golang.org/x/sys/unix # https://github.com/xi2/xz/blob/master/LICENSE \
    --ignore github.com/xi2/xz,golang.org/x/sys/unix # https://github.com/xi2/xz/blob/master/LICENSE
