Fix for error in iOS simulator

[zydeco]

When trying to use in the iOS simulator (17.4, arm64), it fails because it can't load CoreSymbolication from the expected paths:

The exception comes from inside the catch here shows it tries some paths, but not the correct one:

Error: dlopen(/System/Library/PrivateFrameworks/CoreSymbolication.framework/Versions/A/CoreSymbolication, 0x0001): tried: 
'/Users/user/Library/Developer/Xcode/DerivedData/TestApp-apgxxwadlhbgphtscjjkfdhfsniq/Build/Products/Debug-iphonesimulator/CoreSymbolication.framework/Versions/A/CoreSymbolication' (no such file), 
'/Library/Developer/CoreSimulator/Volumes/iOS_21E213/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.4.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/CoreSymbolication.framework/Versions/A/CoreSymbolication' (no such file), 
'/System/Library/PrivateFrameworks/CoreSymbolication.framework/Versions/A/CoreSymbolication' (no such file, no dyld cache), 
'/Library/Developer/CoreSimulator/Volumes/iOS_21E213/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.4.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/CoreSymbolication.framework/Versions/A/CoreSymbolication' (no such file)

However when trying to load from the first path, it doesn't mention trying anything, the error doesn't come from dlopen:

[Remote::Gadget ]-> Module.load("/System/Library/PrivateFrameworks/CoreSymbolication.framework/CoreSymbolication")
Error: unable to find module '/System/Library/PrivateFrameworks/CoreSymbolication.framework/CoreSymbolication'
    at value (frida/runtime/core.js:356)
    at value (frida/runtime/core.js:234)
    at <eval> (<input>:1)

It turns out the call to Module._load succeeds, but Process.getModuleByName fails to find the module with that absolute path (the actual path is prefixed by /Library/Developer/CoreSimulator/Volumes/iOS_21E213/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.4.simruntime/Contents/Resources/RuntimeRoot/, which will vary by iOS version).

I've implemented a quick hack to get around this: CoreSymbolication seems to always be loaded when running apps in the iOS simulator, so loading it can be skipped if it's already there. Another hack could be to use the private Module._load instead.

A more proper solution might be something around Module.load, Process.getModuleByName or gum_store_module_if_name_matches, making it aware that dlopen can succeed when called with an absolute path, but the loaded module's path may be different.
