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.
