crosperf: Filter-in exp_avg_surface_fps in rendering.desktop

Rendering.desktop benchmark which was added into crosperf does not
return results in avg_surface_fps field. Until recently it worked fine.
There is an alternative field in histograms.json "exp_avg_surface_fps"
holding the data.

Add exp_avg_surface_fps in default-telemetry-results.json to filter-in
the benchmark field in crosperf results.

BUG=chromium:1030475
TEST=crosperf with rendering.desktop returns data on chell and lulu
