autoupdate.py: Suppress ValueError exception
When devserver tries to read current update metadata requested by
several concurrent update ping requests, a race condition might happens
which causes the data read could be empty or corrupted. Instead of failing
the autoupdate, this patch suppresses the ValueError exception
intentionally because a new metadata will be calculated accordingly.
