[client] wayland: fix MATE clipboard MIME handling

Browse Source 
Treat either GNOME or MATE copied-files data as preferred over the URI
list fallback. The previous pair of strcmp conditions could never both
be false, so a MATE offer could not replace an earlier URI list.

GNOME and MATE use the same copied-files representation. Generate that
payload once and serve it under both advertised MIME names instead of
overwriting and leaking the first allocation.
