Update ANGLE namespace creation 

Stop using a lambda function to create the namespace,
since not all C++11 features appear to be working.
This allows the Android emulator to support ANGLE.

Test: atest CtsAngleIntegrationHostTestCases (on emulator)
Test: atest CtsAngleIntegrationHostTestCases (on real device)
