[PATCH i-g-t] lib/igt_drm_fdinfo: Handle amdgpu memory stats

[Tvrtko Ursulin <tursulin@igalia.com>]

From: Tvrtko Ursulin <tvrtko.ursulin@igalia.com>

Code so far only handles the clients using the common DRM helper.

Handle the amdgpu driver which uses a slightly different set of keys. More
specifically, outputs drm-memory-<region> instead of drm-total-<region>.

With this added gputop starts showing total memory usage for amdgpu.
