Avoid git warnings on shallow checkout (jaegertracing#5455)

## Which problem is this PR solving?
Many of GH workflows are logging warnings like this:
```
Run make install-test-tools
fatal: No names found, cannot describe anything.
fatal: No names found, cannot describe anything.
fatal: No names found, cannot describe anything.
fatal: No names found, cannot describe anything.
fatal: No names found, cannot describe anything.
```
This is because we typically do a shallow checkout of the repo without
tags.

## Description of the changes
- Check for shallow checkout and don't run `git describe`

## How was this change tested?
- CI `lint`: no warnings logged when calling `make`
```
$ make echo-version
GIT_CLOSEST_TAG=0.0.0
```
