Fix binary path in package-deploy.sh (#5561)

## Which problem is this PR solving?
- A bug was introduced in #5501 where the wrong binary path was used 

## Description of the changes
- Use the right path
- Allow overriding `tar` command since on MacOS the `--sort` option is
not supported (so I had to use `gtar` to test)

## How was this change tested?
These steps succeeded locally:
```
$ make build-all-platforms
$ TARCMD=gtar bash scripts/package-deploy.sh
```
