freebsd: don't run shim delete in deleted dir

fork/exec can fail and log a warning like this in containerd's log:
failed to clean up after shim disconnected error=": fork/exec /usr/local/bin/containerd-shim-[my-shim]: no such file or directory" id=test namespace=default

Passing the bundle path on the command line allows the shim delete
command to run successfully.
