Don't run EmptyDirTaskTests in a Docker container

[dbwiddis]

Signed-off-by: Daniel Widdis widdis@gmail.com

Description

Docker doesn't provide the permissions to test EmptyDirTask. Similar to the Windows OS, the test should not run if it detects that environment.

The primary/reliable/consistent test of whether in a Docker container is the presence of a .dockerenv file in the root directory. There was mention in 2016 that this could in theory be removed in the future but it's still present 6 years later and other proposed alternatives are not consistently valid in 2022. I added two potential backup tests.

The perils of editing on my home machine where I hadn't suppressed save actions and it went crazy. All fixed now.
