kunit: tool: Use qboot on QEMU x86_64
[ Upstream commit 08fafac4c9f289a9d9a22d838921e4b3eb22c664 ]
As noted in [0], SeaBIOS (QEMU default) makes a mess of the terminal,
qboot does not.
It turns out this is actually useful with kunit.py, since the user is
exposed to this issue if they set --raw_output=all.
qboot is also faster than SeaBIOS, but it's is marginal for this
usecase.

Both SeaBIOS and qboot are x86-specific.
