[CI i-g-t 1/5] tests/intel/xe_drm_fdinfo: Print timestamp for debug

[Lucas De Marchi]

xe_spin is capable of writing the timestamp from the GPU side. This is a
good way to compare what we are reading from the fdinfo with what the
GPU is seeing. Example output:

(xe_drm_fdinfo:10404) DEBUG: rcs: spinner ended (timestamp=9817720)
(xe_drm_fdinfo:10404) DEBUG: bcs: spinner ended (timestamp=9755785)
(xe_drm_fdinfo:10404) DEBUG: vecs: spinner ended (timestamp=9653024)
(xe_drm_fdinfo:10404) DEBUG: ccs: spinner ended (timestamp=9722776)
(xe_drm_fdinfo:10404) DEBUG: rcs: sample 1: cycles 19513436, total_cycles 130596422980
(xe_drm_fdinfo:10404) DEBUG: rcs: sample 2: cycles 29331470, total_cycles 130606141449
