[PATCH 11/13] qemu: add the nixosfi-qemu-build defconfig

From: Daniel Gomez <[email protected]>

Add a defconfig that exercises the QEMU build on the nixosfi imageless
backend. It enables CONFIG_QEMU on top of a nixosfi qsu guest, so the
controller builds QEMU from the upstream tree and installs it sudolessly
under the controller data path (qemu-destdir).

No qemu binary path is set by hand: with CONFIG_QEMU enabled,
QSU_QEMU_BINARY defaults to QEMU_BIN_PATH, which derives from
QEMU_INSTALL_DIR, so the binary qsu execs is exactly the one the qemu
role installs. Building QEMU and pointing qsu at it is therefore a single
knob.
