util/scripts: add some support scripts
These scripts were bit-rotting on my box and may be useful for somebody else.
no-fsf-addresses.sh removes various FSF addresses from license headers
find-unused-kconfig-symbols.sh points out Kconfig variables that may be
unused. There are some false positives, but it serves as a starting point.
