More specific libdrm error message

[Xie, AlexBin]

Hi Emil,


Thanks for the advice. I noticed that you have changed some tests using drmGetDevices2.

I mark this to my to do list.


Thanks,

Alex Bin Xie

Thanks Edward.

Xie, suggesting to run almost anything as root is a bad idea ;-)
Instead one could auth, in order to have the correct permissions.
Alternatively can use the renderD node all together.

Idea for future work:
Would be even better to use drmGetDevices2 to fetch all the devices
and use the correct node since card0/renderD128 is not guaranteed to
be a amdgpu one. Or maybe even run all the amdgpu devices through the
tests ?

Please correctly wrap commit messages and code.

Thanks
Emil
