[INTERNAL] jQuery.sap.global: XHR fix for jQuery issue #2068

With jQuery 1.11.1 the creation of the XHR object has been changed so
that it validates the supported HTTP methods and decides whether to
create a standard XHR or and ActiveXObject. In this function the methods
PATCH and MERGE are not listed and so the fallback to ActiveXObject
takes place.
