Correct ModFlagBehavior for Aarch64 on LLVM-15
When building with Fat LTO and BTI enabled on aarch64, the BTI is set to `Module::Min` for alloc shim but is set to `Module::Error` for the crate. This was fine when we were using LLVM-14 but LLVM-15 changes it's behaviour to support for compiling with different `mbranch-protection` flags.
