[Drbd-dev] [PATCH] containers: add commands to correct SELinux context

When running the entry.sh script with RAM-based module loading method, the
generated modules acquire the 'var_lib_t' context by default on certain systems.

This patch adds commands to correct the context to 'modules_object_t'
to allow seamless module loading on SELinux-enabled systems.
