Justin Lecher 7fe27fc693 Use posix compliant tail syntax
homebrew allows using gnu coreutils on MacOS. Therefore we should
comply with posix standards

```bash
$ mas help | tail +3
tail: cannot open '+3' for reading: No such file or directory
$ type tail
tail is /usr/local/opt/coreutils/libexec/gnubin/tail
```

Switching to posix compliant `-n` syntax is compatible with UNIX and GNU tooling.

```bash
$ mas help | /usr/bin/tail -n +3 | wc -l
18
$ mas help | tail -n +3 | wc -l
18
```
