Merge from widevine repo of http://go/wvgerrit/14669
This fixes two timing-related test failures when running the OEMCrypto
tests in the CE test suite. The failures were caused by the TestHost
Clock implementation, which is a fake. Since there is no clear reason
for OEMCrypto/mock to rely on wvcdm::Clock, this replaces it with
time(NULL). Incidentally, this also makes the time source consistent
with the tests themselves, which were already using time(NULL).

OEMCrypto_DeleteUsageTable used to return an error on every call
because UsageTable::Clear always returned false. Since there is no
error checking that Clear can do, its return type has been changed to
void, and DeleteUsageTable now returns OEMCrypto_SUCCESS for all
calls.
