Michal Privoznik 9f5c6d06ad spice/gl: Enable dmabuf only for spice >= 0.13.1
After 474114b7 the dmabuf feature is enabled whenever spice
greater than or equal to spice 0.13.0 is found. This is because
two new functions are required: spice_qxl_gl_scanout and
spice_qxl_gl_draw_async. These were, however, introduce in 0.13.1
release. Well, technically they haven't been released yet, but
for sure they are not going to be part of 0.13.0 release (for the
ABI stability sake).
