cheets_GTS: GTS4.1r2 uses new test case counting logic.

*** DO NOT MERGE TO M58 ***
(unless you deploy 4.1r2 to M58)

The new GTS displays the test counts in the same way as the latest CTS 7.1.
Switch the flag to the new mode.

BUG=b:37652396
TEST=cheets_GTS.4.1_r2.GtsGmscoreHostTestCases reports test count ~90 or ~180.
