Add possibility to run .cicd scripts from different environments

### With FORCE_LINUX=true, you can run the Docker version in `build.sh` an `package.sh` scripts

When running the scripts from Mac OS X, it was always picking up the Darwin conditional
paths in the script. `FORCE_LINUX=true` can be used on a Mac OS X environment to run
the scripts.

### Fix shell expansion in `package.sh`

In the packaging script, there is a Docker pre command that add executable bit permission
on *.sh scripts in the `build/packages` folder. However, without the escaping, the shell
expansion was performed in the `package.sh` script execution directly instead of being
delayed so that the expansion is performed inside the `docker run` call!

I suspect this worked in your CI system because execution of `package.sh` in performed in
such way that filesystem layout of `package.sh` and filesystem layout of `docker run` were
the same and as such, the expanded `chmod 755 file1.sh file2.sh` command was correctly
working inside the container.

The shell expansion via the `*` is now escaped which correctly delays the expansion until
it's in the `docker run` execution environment.

### Conditional buildkite-agent upload

Now, the upload task is performed only  if BUILDKITE env is set to `true`, so it's possible
to run the script without having to upload the actual package.
