Update volume mount examples and dockerHome variable from
the old /var/lib/srv/$USER/docker layout to /srv/$USER/docker.
- README.md: update volume path references to /srv/$USER/docker
README.md
rootfs/usr/local/bin/copy
rootfs/usr/local/bin/healthcheck
rootfs/usr/local/bin/symlink
Aligns README install/run snippets with the new convention split:
rootfs/ for Dockerfile-build content (image filesystem), volumes/
for docker-compose host bind-mounts. Compose mounts, host bind
paths, and runtime data dirs are renamed; Dockerfile COPY/ADD
sources (where present) are preserved.
