add kernel target for RustyHermit

Browse source 
Currently, we are thinking to use *-unknown-none targets instead
to define for every platform our own one (see hermitcore/rusty-hermit#197).
However, the current target aarch64-unknown-none-softfloat doesn't support
dynamic relocation. Our kernel uses this feature and consequently
we define a new target aarch64-unknown-hermitkernel to support it.
