Commit 3c07a01c4 (xwayland: Use xdg-output name for XRandR) changed the
logic to use a fixed sized buffer allocated on the stack to pass to
RROutputCreate() which would then copy it.
Valgrind complains about this:

This is actually harmless, but also simple to avoid by just initializing
the content of the array with zeros, so let's just fix that.
