[sb2] Delay creation of run symlink creation for /var/run

A link to target_root/run is needed from /tmp/sbox_session_dir/run,
which will be where /var/run symlink points. The symlink was created
too early and ended up pointing to the host's /run directory. This
ended up causing problems in sb2 path resolution.
