build_packages: use setfiles to label the system

setfiles can be used to directly set the SELinux labels on a root filesystem based on the values in file_contexts.


$ tar --selinux --xattrs -xf $(readlink -f docker\:20.10.torcx.tgz)
$ find -context "*unlabeled*"
$

build_packages Outdated
# build and label the system before generating torcx image.
info "Label the build root"
sudo chroot "${BOARD_ROOT}" bash -c "cd /usr/share/selinux/mcs && semodule -s mcs -i *.pp"
sudo setfiles -Dv -r "${BOARD_ROOT}" "${BOARD_ROOT}"/etc/selinux/mcs/contexts/files/file_contexts "${BOARD_ROOT}"

setfiles is a cool idea, but doing it in build_packages is not useful, because the images are not built from the files in BOARD_ROOT. This would have to happen somewhere in build_image and in build_torcx_store.

`setfiles` can be used to directly set the SELinux labels on a root
filesystem based on the values in `file_contexts`.

Can you rather rebase? My PR only did the labeling for /etc which was what I needed to prevent overlay upcopies but most of your PR is still relevant, to fix any /usr labels and also produce correct torcx labels.
