cibuild.sh: decouple -b option to do run_builds only

1. In nuttx and apps PR check build, github action/jenkins/travis CI would
checkout repos accordingly. So decouple -b option to do run_builds only.
2. And if do builds starting from testing repo, call cibuild.sh as below:
./cibuild.sh -i -s -b check or ./cibuild.sh -i -s -b full
