Charmcraft fails to build due to lack of Git
Metadata
Current evaluation
Resolved as a build-environment configuration issue: the reporter fixed the failure by adding git to parts.charm.build-packages in charmcraft.yaml.
Resolution: closed not a bug
Reason: The build environment lacked Git rather than Charmcraft failing to install it. The reporter confirmed that declaring git under parts.charm.build-packages resolved the same failure documented in canonical/charmcraft#490.

Issue body
Hi there!
I have found an issue in which charmcraft fails to pack the operator when the package specification in the `requirements.txt` contains the reference to the git repository in example:
` git+https://github.com/canonical/operator/#egg=ops`
Lxd version : `4.0.8`
Charmcraft version: `1.2.1`
My `charmcraft.yaml` file has the following contents:
```
# Learn more about charmcraft.yaml configuration at:
# https://juju.is/docs/sdk/charmcraft-config
type: "charm"
bases:
- build-on:
- name: "ubuntu"
channel: "20.04"
run-on:
- name: "ubuntu"
channel: "20.04"
```
The error logs are following:

```
When I specify the ops module using the standard notation `ops >= 1.2.0` everything works well.
Is there any reason that the Git is not installed on the build machine?
Thanks a lot!

Same missing-git build failure; adding git as a charm build package was the confirmed workaround.
