mkosi only mounts live-image/ as /work/src, so the postinst couldn't
reach the repo-root bin/vetting-agent.linux-amd64 — the build failed
in CI with `install: cannot stat '/work/src/bin/vetting-agent.linux-amd64'`.
The Makefile now copies the prebuilt agent into mkosi.extra/, which
mkosi merges into the image root automatically. The postinst is
reduced to creating the multi-user.target.wants symlink.

mkosi refuses to run a non-executable postinst. git was tracking it
as 100644 because it was added from Windows (no POSIX exec bit on the
FS), so CI saw a non-executable file even though WSL/Linux had been
treating it fine locally. Same fix applied earlier to install.sh +
pxe-setup.sh.
