16: Add Aarch64 test r=stlankes a=jschwe

This PR adds an aarch64 artifact of the hermit application (for use with the github workflow) that will exit once it reaches the point up to which the kernel currently works. Expected Output is something like:

$ qemu-system-aarch64 -display none -smp 4 -m 1G -serial stdio -kernel target/aarch64-unknown-hermit-loader/debug/rusty-loader  -machine raspi3 -semihosting

This test compiles the rusty-loader with an application artifact compiled from
    The artifact is technically the rusty_demo artifact, since the hello_world artifact
    didn't work for me.
    ~~This is most likely due to the loader still being brittle.
    I suspect that the copying process is buggy, since (un)commenting simple things
    such as log messages in rusty-loader will break or fix entry into the kernel.
    Until this is fixed this workflow will probably fail sometimes.~~

Update: Commit ae3308cb

 changes the way the Stack pointer is set and this seems to fix the issues I'd been having.
