xwayland: Fix compiler warning in GLAMOR Xv 

XvWindowMask is defined as 0x00020000 and cannot fit in the XvAdaptor
type which is defined as an unsigned char, thus causing a compiler
warning:

  xwayland-glamor-xv.c: In function ‘xwl_glamor_xv_add_adaptors’:
  xwayland-glamor-xv.c:339:16: warning: large integer implicitly
  truncated to unsigned type [-Woverflow]

This XvWindowMask value is actually not used for XvAdaptor itself but by
the server in its xf86xv implementation, so we don't even need that mask
in our xwayland-glamor-xv implementation.
