.profile.d/path.sh is a name which is too generic

The Heroku documentation at https://devcenter.heroku.com/articles/buildpack-api#profile-d-scripts says :
_"During startup, the container starts a bash shell that source’s all .sh scripts in the .profile.d/ directory ..."_

So if several `.sh` scripts are generated in .profile.d by multiple buildpacks, they should be named distinctly.

I suggest to rename `path.sh`to `salesforce_cli_path.sh`.
