screenshooter: silence a warning

screenshooter.c: In function ‘recorder_binding’:
screenshooter.c:509:5: warning: ‘listener’ may be used uninitialized in
this function [-Wuninitialized]

This was not really a problem so far, because the variable was
uninitialized only in the case where Weston had no outputs.
