Disable CFI verification for unit tests that are using gtest+gmock

Apparently, the CFI verification crashes unit tests that
are using gtest+gmock. Interestingly, those tests succeed for 32-bit
binaries, and fail for 64-bit binaries.

Bug: 71739588
Test: Running the 64-bit version of the unit tests in test/run_unit_tests.sh
