RFR: 8263436: Silly array comparison in GaloisCounterMode.overlapDetection

[Aleksey Shipilev]

SonarCloud reports:
  Use "Arrays.equals(array1, array2)" or the "==" operator instead of using the "Object.equals(Object obj)" method.

        } else if (!src.isDirect() && !dst.isDirect()) {
            if (!src.isReadOnly()) {
                // If using the heap, check underlying byte[] address.
                if (!src.array().equals(dst.array()) ) { // <--- here

Additional testing:
  - [x] Linux x86_64 fastdebug `jdk_security`
