Kevin Veen-Birkenbach 2c3b29ee98 test(e2e): full virtualized build+boot+unlock QEMU harness ...

Opt-in via LIM_E2E_QEMU=1. Models the whole process on a virtio VM (the
Pi's USB-gadget net can't be emulated, so it models the software stack,
not the board): builds a LUKS image carrying the real lim initcpio Tor
artifacts, boots it in QEMU rootless, lets the real netconf/tor/dropbear/
encryptssh chain publish the onion, delivers the passphrase over Tor, and
asserts the boot-ok marker on the serial console. Supports a private
offline Tor network via chutney.

The pure command builders (config.qemu_argv/kernel_cmdline/ssh_argv,
qemu_binary), the env parser, and drift guards that keep build_image.sh
aligned with the harness run in the normal suite — no QEMU/root/network.

The build stage needs root; harness.py primes sudo up front, keeps the
credential warm, and reclaims work-dir ownership on every exit path so
the pytest tmp cleanup never trips on root-owned files. QEMU stderr is
captured so an early exit is debuggable, and each teardown step is
fault-isolated so none masks the real error.
