libcontainerd/supervisor: replace BurntSushi/toml with pelletier/go-toml
Taking the same approach as was taken in containerd

The new library has a slightly different output;

- keys at the same level are sorted alphabetically
- empty sections not omitted (`proxy_plugins`, `stream_processors`, `timeouts`),
  which could possibly be be addressed with an "omitempty" in containerd's struct.
- empty slices are not omitted (`imports`, `required_plugins`)

After sorting the "before" configuration the diff looks like this:

```patch
diff --git a/config-before-sorted.toml b/config-after.toml
index cc771ce7ab..43a727f589 100644
