[PATCH libdrm 3/3] amdgpu: A new option to run tests on render node

[Alex Xie]

Tested:
1. As root, tests passed on primary.
2. As root, tests passed on render node.
   BO export/import test was skipped
3. As non-privileged user, tests failed on primary as expected.
4. As non-privileged user, tests passed on render node.
   BO export/import test was skipped
