commit 287638db59d0938ceb263fcef1bf0c28eefb2033

xwayland/glamor/gbm: Set GBM_BO_USE_LINEAR if only LINEAR modifier is supported
Some drivers might not support explicit format modifiers. On these
drivers `gbm_bo_create_with_modifiers()` will fail and the
`gbm_bo_create()` code path will be used instead.
In this case, if the LINEAR modifier is advertised (and the INVALID
modifier is not) add the `GBM_BO_USE_LINEAR` flag.
