[jdk11u-dev] RFR: 8270199: Most SA tests are skipped on macosx-aarch64 because all executables are signed

[Andrew Lu]

I backport this for parity with 11.0.24-oracle.
test/hotspot/jtreg/testlibrary_tests/TestMutuallyExclusivePlatformPredicates.java
Backport to the origin file.
Add backport to JDK-8241951, since it is modified after this backport.
