ANDROID: gki_defconfig: initialize locals with zeroes

Browse Source 
This patch switches compiler-based stack initialization from 0xAA
to zero pattern, resulting in much more efficient code and saner
defaults for uninitialized local variables.

Bug: 154198143
Test: run cuttlefish and observe the following lines in dmesg:
      test_stackinit: all tests passed!
      test_meminit: all 130 tests passed!
