Add `Sandbox::AllocateAndTransferToSandboxee` utility function.
...
Create a utility function to copy a hostcode local buffer into the sandboxee. This combines the following steps into one API call:
1) Create a SAPI variable backed with the hostcode local buffer
2) Allocate the SAPI variable in the sandboxee's memory space
3) Transfer the SAPI variable into the sandboxee's memory space
The function returns a `std::unique_ptr` wrapped `sapi:✌️ :RemotePtr` which points to the address of the buffer in the sandboxee's memory space.

Return ENOSYS instead of hard denying clone3
...
It's currently not possible to properly inspect arguments of clone3 via seccomp.
As userspace (notably glibc) started using clone3, other sandbox solutions (e.g. in Firefox and Chrome) switched to returning ENOSYS for that syscall, which usually will result in libraries falling back to clone/clone2.

This change requests an exit from the sandboxee and then awaits the result either with a timeout of 1 second (the grace period) or else with infinite duration - which would then report the timeout again.
