[PATCH 2/8] Documentation: mention scripts/diffconfig tool

[Randy Dunlap <rdunlap@xenotime.net>]

Documentation: Mention scripts/diffconfig as a tool to compare config files

The kconfig documentation suggests using plain 'diff' to compare
config files and then adds "Yes, we need something better here".
"a717417 kconfig: add diffconfig utility" added what that comment was
looking for.
