Subject: [PATCH] Workaround for mount plugin with a GLib-mounted encrypted
 volume (#2060)

`Solid::StorageAccess::accessibilityChanged` isn't emitted when an encrypted volume is mounted by GLib/GIO (e.g., through pcmanfm-qt). This is a workaround.

Closes https://github.com/lxqt/lxqt-panel/issues/1639
