unified list command for all scripts

e.g. ./build boot roms list
./update blobs inject listboards
./build boot list
./build clean list

also this is now possible:
./build list
or maybe
./update list
^ would list directories in resources/scripts/build
and resources/scripts/update respectively

this script is added:
resources/scripts/build/command/options

call it like so, e.g.
./build command options resources/coreboot

this script is now used, for list functions in
other scripts.
