xwayland: Fix crash on weston shutdown

Browse Source 
commit e7fff215ad made initializing the
selection_listener conditional, but didn't make its clean-up
conditional at shutdown.  Simply initializing the listener's list
link at init time makes this harmless.

To see this, run weston -Bheadless-backend.so and then connect to it
with an X client.  When killing weston it will attempt shutdown but
die with a segfault.
