Remove Object.prototype.inspect

I'm not sure if this used to be added by node, but I can't find it
anywhere in the docs or code in recent versions.  It was also causing
the following warning (due to a conflict with util.inspect):

./util.js:77: WARNING - assignment to property inspect of Object.<string,*>
found   : function (*, boolean=, number=, boolean=): string
required: function (this:Object): ?
util.inspect = function(object, showHidden, depth, colors) {};
^
