winsys/amdgpu: use DMA_BUF_SET_NAME_B if available
Give a name to dma-buf. This name appears in /sys/kernel/debug/dma_buf/bufinfo
and could be useful to debug dma-buf:
Dma-buf Objects:
size flags mode count exp_name ino name
00606208 00000002 00080007 00000003 drm 00192014 2321705-glxgears
The name is only added to non-shared buffer, to avoid overwriting
an existing name when exporting an imported buffer (otherwise all
dma-buf will pretend to be created by XWayland).
