Makefile cleanup and travis-ci s3 deploy (#6329)

- pulls more of the travis-ci s3 deploy into the repo so we can potentially migrate to another CI system
 - fixed the sizes output and added verbose compiler version to cmake (#6322)
 - fixed filenames for firmware uploaded to s3 (was broken by the changes yesterday)
 - fixed some broken git version display in cmake
 - Makefile organization
 - simplified .travis.yml
 - added a print to know which config the nuttx patch was being applied to
 - docker_run.sh now respects PX4_DOCKER_REPO for setting the docker image, but defaults to the good production nuttx image
