Zero check - fail on wget

zero check fails to pass when using wget version does not contain the PATCH part.

```
$ wget --version  | grep -E '^GNU Wget'
GNU Wget 1.14 built on linux-gnu.
```

The regex for the wget looks for expect the version to be in format `MAJOR.MINOR.PATCH`.

Amazon Linux 2 for example comes with wget 1.14, and as shown above it fails on the test.
