move script/*/* to script/

there are only two scripts under script/ now, and there
probably won't be many more. lbmk's design has simplified
to such a degree that the two-level directory structure is
no longer necessary.

the existing command structure has not changed. for example:

./build roms list
./update trees -f coreboot default

these will still work, but the symlinks to "build" are now
strictly for backwards compatibility; they may be removed
at a later date, but i'll keep the current design for now.

this also leads to a quirk, for example:

./build roms all
./update roms all

these now do the exact same thing, whereas "./update roms all"
would have previously been an invalid command.
