Fix --containers with selinux
I am getting this error when running aib-osbuild-mpp in the container:
{"msg":"exec container process
/vcs/tyt/automotive-image-builder/mpp/aib-osbuild-mpp
: Permission
denied","level":"error","time":"2024-05-16T15:44:09.059782Z"}
Due to this AVC:
AVC avc: denied { entrypoint } for pid=1062421 comm="3" path="/vcs/tyt/automotive-image-builder/mpp/aib-osbuild-mpp" dev="nvme1n1p3" ino=115804 scontext=system_u:system_r:unconfined_t:s0:c>
I think this is because its unnecessarily (in the mpp case) running as unconfined_t, and we can avoid this by not using that in the mpp container.
