data: install snapcraft logo in /usr/share/snapd (#12388)

This commit ensures that the snapcraft icon is shown in the lock screen notifications. Unfortunately, to make it work it requires to be modified in the .deb package; it seems that there is no way of doing this in the snap package because the required change must be set in the "first" .desktop file, and /usr/share(/applications) is before than /var/lib/snapd/desktop(/applications) in the XDG_DATA_DIRS order.
