containerd shim sporadically fails to mount the rootfs [1, 2].

The error originates within the containerd mounter during the shell command execution:

mount_nullfs: /run/containerd/io.containerd.runtime.v2.task/buildkit/nbxh1elkrwu64xuir6pmmjrtw/rootfs: Resource deadlock avoided

Currently, the sporadic "mount_nullfs: /path/to/rootfs: resource
deadlock avoided" error occurs during containerd shim task creation.
The exact reason for this error is unknown, but a mounter that
executes the system call instead of running a shell command seems to
fix the problem.

This change replaces the containerd's mounter with `moby/sys/mount`
