fix(config): move init services from /usr/lib/init.d to /etc/init.d

Config [[files]] entries for init services used /usr/lib/init.d/ paths,
which get silently overwritten by package staging (Layer 2 over Layer 1).
Per AGENTS.md, config overrides MUST use /etc/init.d/ so the init system's
config_for_dirs() gives them priority over package defaults.

Fixes mini image debug console failure (getty: failed to open TTY
/scheme/fbcon/3: No such file or directory) caused by base package's
31_debug_console.service overwriting minimal.toml's debug scheme override.
