Cache quota size definition tests depend on the host system
## Summary
[//]: # (Summarize the bug encountered concisely)
Since !563 BuildStream checks for the available space on disk. This means that certain configurations can raise exceptions on systems that have too little
storage to accommodate the configurations the test cases ask for.
## Steps to reproduce
[//]: # (How one can reproduce the issue - this is very important)
Have a disk that's more than 50% full and run `./setup.py test --addopts '--no-cov tests/artifactcache/expiry.py::test_invalid_cache_quota[50%-True]'`.
## What is the current bug behavior?
[//]: # (What actually happens)
The test fails.
## What is the expected correct behavior?
[//]: # (What you should see instead)
The test should succeed.
## Relevant logs and/or screenshots
[//]: # (Paste any relevant logs - please use code blocks ``` to format console output, logs, and code as it's hard to read otherwise. You can also add a Snippet and link it here. Check the markdown giude on Gitlab for further tips)

Program stderr was:
Error loading user configuration: Your system does not have enough available space to support the cache quota specified.
You currently have:
- 0B of cache in use at /home/valentin/repos/buildstream-2/tmp/test_invalid_cache_quota_50__T0/cache/artifacts
- 269G of available system storage
```
## Possible fixes
[//]: # (If you can, link to the line of code that might be responsible for the problem)
Mock out calls to `os.statvfs` in `tests/artifactcache/expiry.py` (though only for those tests that assert parsing works).
## Other relevant information
[//]: # (Add the BuildStream version. Substitute below the "x" by "1", "2" or the right version. Add more than one version if necessary)
