[Electra] Unable to spawn apps using dyld3

[AeonLucid]

Same issue as #176, but for newer versions.

Device: iPhone 6 iOS version: 11.3.1 Jailbreak: Electra-mptcp Frida tools & server: 12.0.3

(1) Commands:

• frida-ps -U -f com.apple.DocumentsApp (Stock Files app)
• frida-ps -U -f com.toyopagroup.picaboo (Snapchat)

Result:

Failed to spawn: unexpectedly timed out while waiting for process to suspend

(2) Commands after the above error while keeping the spawned app open:

• frida-ps -U -n Files
• frida-ps -U -n Snapchat

Result:

Failed to attach: unexpected error while probing dyld of target process

If you open the app manually, it attaches fine at (2).

it's because hardware breakpoints don't work from iOS 11.3.1 up to and including iOS 11.4.1

we currently rely on hardware breakpoints for spawn and early instrumentation on i/macOS

currently working on implementing software breakpoints for those iOS versions
