code review 5502047: build: use go command during build

build: use go command during build

If something goes wrong, it should suffice to set
USE_GO_TOOL=false in env.bash to fall back to the
makefiles.  I will delete the makefiles in January.

it drops by 10% (2 seconds out of 21) for building all the Go code.
when we do builds in parallel it will get better.
