[PATCH] scripts: container.sh: explicitly pass build dir as volume

[PATCH] scripts: container.sh: explicitly pass build dir as volume

[Ahmad Fatoum]

For cases, where KBUILD_OUTPUT/LG_BUILDDIR may be a symlink, processes
running inside the container may not have the necessary permissions to
follow it.

Fix this by calling realpath on it and explicitly registering it as
volume.
