Brand rbsh's banner and getty's greeting as Foundry OS

rbsh (interactive): 'Foundry OS shell (rbsh) on Rustbelt 0.21.0. Type
`help` for commands.' (kernel name and release from uname), then the
drives. getty: 'Foundry OS getty: shell on this terminal'. run-headless
expects the new greeting on hvc0; test-reference, which boots the kernel
repo's own getty, passes GETTY_GREETING with the old one.
