Refine TwoHundredEntries tests

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/58440

This CL modifies the oemcrypto test TwoHundredEntries so that it
attempts to create more than 200 entries.  A device is allowed to fail
when such an attempt is made, but it must return an insufficient
resources error.

The test then verifies that each of the entries that were succesfully
created can be used to reload its license and the keys can be used for
decryption.

It then shrinks the usage table header, and verifies that the
remaining licenses can still be used for decryption.
