gbm/dri: Fix sign-extension in modifier query When we were assembling the unsigned 64-bit query return from its two signed 32-bit component parts, the lower half was getting sign-extended into the top half. Be more explicit about what we want to do. Fixes gbm_bo_get_modifier() returning ((1 << 64) - 1) rather than ((1 << 56) - 1), i.e. DRM_FORMAT_MOD_INVALID.
