fix(init): pass timezone via env var instead of reading missing file

init-root.sh was reading timezone from /etc/box-assembled.ini, but that
file is only copied into the container after init hooks complete. Pass
BOX_TIMEZONE as an env var through pre_init_hooks so it's available when
init-root.sh runs.
