Make dumpdecrypted work on iOS 9.3.3

Thanks: http://iosre.com/t/make-dumpdecrypted-work-on-ios-9-3-3/4876

If you come across Killed: 9 too:

FunMaker-SE:/User/Downloads root# DYLD_INSERT_LIBRARIES=dumpdecrypted.dylib /var/containers/Bundle/Application/6476E127-11B7-4861-B742-D781D0DBBD3A/ChinaUnicom4.x.app/ChinaUnicom4.x
Killed: 9

Then running the script as mobile may do the trick:

FunMaker-SE:/User/Downloads root# su mobile
FunMaker-SE:/User/Downloads mobile$ DYLD_INSERT_LIBRARIES=dumpdecrypted.dylib /var/containers/Bundle/Application/6476E127-11B7-4861-B742-D781D0DBBD3A/ChinaUnicom4.x.app/ChinaUnicom4.x
