test: skipIfInspectorDisabled cluster-inspect-brk

When configured --without-ssl the inspect-brk option will not be available and the process will exit with a exit value of 9 "Invalid Argument/Bad option". This commit adds a skipIfInspectorDisabled check since --without-ssl implies that no inspector support is build as well.
