drm_hwcomposer: Increase failure time for acquire fences

Increase the acquire timeout to effectively 500ms before failing
a frame. Also log every 100ms so we're still able to track long
fence waits.

BUG=chrome-os-partner:46301
TEST=Tested on smaug with cts test, saw timeout messages, but not
     failures
