Purposal for fix on issue 6251 - max upload filesize (snipe#7930)

* Added a check and sed to startup.sh for managing max upload size inside the docker container. Issue encountered in 6251

* Changed startup.sh to bash instead of sh to have better variable control. Changed single ticks to double ticks for the sed so that the variable PHP_UPLOAD_LIMIT is expanded

docker/startup.sh
