Exclude AIX tests which deliberately fails on AIX

ref #5854

Looks like this is a test which deliberately fails on AIX

Testcode https://github.com/adoptium/jdk8u/blob/release/langtools/test/tools/javah/ReadOldClass.sh

# set platform-dependent variables
OS=`uname -s`
case "$OS" in
  SunOS | Linux | Darwin | CYGWIN* )
    PS=":"
    FS="/"
    ;;
  Windows* )
    PS=";"
    FS="\\"
    ;;
  * )
    echo "Unrecognized system!"
    exit 1;
    ;;
esac

uname -s on AIX machines returns AIX

Will cherry pick into the release branch
