Merge ~hyask/auto-upgrade-testing-specifications:skia/fix_var_crash_hanging into auto-upgrade-testing-specifications:main

[Skia]

This fixed my bionic to focal upgrade tests locally, should also help on Jenkins.

Sample output:
```
#### Checking /var/crash ####
Ensuring `whoopsie` is finished running
 Error waiting for `whoopsie` (Command '['sudo', 'systemctl', 'start', 'whoopsie.service', '--wait']' timed out after 119.99996964399999 seconds), continuing anyway
 stdout: None
 stderr: None
Today is 2024-02-02
Failed to load ignore list from `scripts_data.json`: 'NoneType' object is not subscriptable
PASS: /var/crash is empty (good)
#### /var/crash checked (exit_code: 0) ####
```
