    build: Make LSan exit with code 23 on leaks
    
    This allows us to catch memory leaks in the expected-fail script tests.
    Previously, we could not distinguish between LSan exiting with a nonzero
    code and the test's expected failure with a nonzero code. Arbitrarily
    designate 23 as LSan's exit code and check for it.
