The game Batman: Arkham Knight expects OpenGL behavior
with sample mask and multisampling which is different
from the Vulkan one.
This workaround fix changes key->ignore_sample_mask_out
value that is used for
prog_data->uses_omask definition in brv_fs.cpp(9740)
In that way prog_data->uses_omask also changes it value
and the cloak stops flickering.
