uxa: Wakeup 3s after the last rendering to reap the bo-cache

libdrm expires its bo 2s after entry into the cache, but we need to free
a buffer to trigger the reaper. So schedule a timer event to trigger 3s
after the last rendering is submitted to free any resident bo during
long periods of idleness.
