winsys/amdgpu: keep has_local_buffers true for userq

Browse source 
In case of userqueue, kernel bo kms_handle will not hold fences for non
shared bo. Non shared bo fences are taken care within mesa. Hence need
to copy the data to another shared buffer for export.

Keeping has_local_buffers true for userq will make non shared bo to
be copied to shared bo for export in si_texture_get_handle().
