Expand description

Explanation of the (stale kconfig) tag. Mirrors UNTRACKED_KCONFIG_EXPLANATION so the kconfig tag pair shares one shape — every kconfig-status legend in the informational trio (EOL / UNTRACKED / STALE) is now a const surfaced via a *_legend_if_any helper. Verbatim wording preserved from the prior inline eprintln! in kernel_list so existing operators see no behavioural change.
