i#4924: Enable drcachesim -test_mode in release builds

Makes the -test_mode option, which runs the invariant_checker tool, available in release builds. This fixes the drcacheoff.rseq test failures on GA CI when rseq is actually available in our upgrade to Ubuntu 20.04.

Removes the test failure ignore rule for Jenkins as this also fixes the AArch64 failure for the same test.

Fixes #4924 (closed) Issue: #4924 (closed), #4953 (closed)

Forgot to say that I tested on my ubuntu20.04 VM and on an aarch64 machine.

The windows 32-bit test failure is the type_is_instr flaky assert: #3320.
