Revert^4 "Add patchoat test"

This reverts commit 1fb8d5ee.

Skip the patchoat test on the build server where the build is not
using read barriers. Read barriers (or CMS/MS garbage collector) are
required for the --force-determinism feature used by the test.

Test: ./art/test/testrunner/run_build_test_target.py art-gtest-debug-gc
Test: make test-art-host-gtest-patchoat_test
Test: make test-art-target-gtest-patchoat_test
