util/lint/kconfig_lint: Exclude site-local directory by default

The site-local directory is not checked into the coreboot tree, so this
change excludes it by default. By adding the site-local directory,
an issue could be missed in the rest of the coreboot tree.

This change also adds a new command-line argument of -S or --site_local
that re-enables the site-local checking.
