debos: rootfs: Use mate-polkit, not ukui-polkit

ukui-polkit is currently randomly selected to provide
polkit-1-auth-agent (needed by nm-connection-editor), but through
libopencv-imgcodecs410 => libgdal36 => libavif16, it pulls in a lot of
potentially patent encumbered dependencies such as libaom1, libdav1d7,
libde265-0, libgav1-1, librav1e0.7, libsvtav1enc2. It also generally
pulls in a lot of dependencies. Select the lighter mate-polkit instead.

Saves about 200MiB and drops libaom1, libde265-0, libgav1-1,
librav1e0.7, libsvtav1enc2 from rootfs.
