Updated integration test to handle unlimited license durations.

Browse Source 
[ Merge of http://go/wvgerrit/128046 ]

Test case WvCdmStreamingUsageReportTest.WvCdmStreamingUsageReportTest
was failing comparing "license duration" values returned when querying
for key information for licenses with unlimited "rental duration".

This is due to the new license duration model used for V16 licenses.

From the Widevine MediaDrm doc for "LicenseDurationRemaining":

  For OEMCrypto v16+ (Android 11 and later), license duration is no
  longer being enforced. If rental duration is set to never expire,
  ”9223372036854775807” (LLONG_MAX) will be returned.

Similarly, the test has been updated for "playback duration" queries
of the same case.

Bug: 163542905
Test: cdm_extended_duration_test
