deny-mmap for DYLD_INSERT_LIBRARIES on Simulator Process

It looks like the Simulator.app binary is now signed as of Xcode 7 as the following occurs in instruments-without-delay when using the build script:

./build.sh test <SIMULATOR-UDID>

The message that we get from the kernel is: 7/23/15 12:22:52.000 PM kernel[0]: AMFI: Simulator(pid 72600) - [deny-mmap] mapped file has no team identifier and is not a platform binary: /Users/lawrencelomax/src/instruments-without-delay/build/SimShim.dylib

This causes a crash:

instruments-without-delay on Xcode 7

instruments-without-delay uses the DYLD_INSERT_LIBRARIES environment variable to shim from the instruments command line all the way down to ScriptAgentShim which is the iOS Simulator service responsible for interfacing UIAutomation JavaScript with the native UIAutomation.framework. It uses a stack of shims, starting at the instruments executable, going through Simulator.app. It is an essential part of ios-driver as it removes a pesky 200ms delay that drastically slows down the process of executing end-to-end tests. This is a fixed cost that would occur on every command.

Other than a few things being moved around and renamed in Xcode 7, there is the new issue of the codesigning of the Simulator app that triggers amfid whenever an unsigned image is loaded. This essentially means that we can't use DYLD_INSERT_LIBRARIES on the Simulator Process with SimShim

It is however, possible to inject these environment variables at the launchdaemon level. There is a plist fo
