Fixed podman-mac-helper uninstall to remove docker.sock symlink

[tnk4on]

Fixed to remove not only plist but also /var/run/docker.sock(symlink) when podman-mac-helper uninstall command is executed.

Fix: #20650 and podman-desktop/podman-desktop#5324 .

Does this PR introduce a user-facing change?

Fix `podman-mac-helper uninstall` command does not remove docker.sock symlink.

@baude @ashley-cui @n1hility PTAL

[rhatdan]

@tnk4on Yes that looks good, but can you use:
if errors.Is(err, fs.ErrNotExist) {

Rather then
if os.IsNotExist(err) {

The errors.Is it the new way to handle this.
