Build is emitted into the wrong folder when using Docker

[eweilow]

Describe the bug
The build output is emitted into <currentDir>/<absolutePathOfCurrentDir>.
This is a regression in version 5.21.0, as it doesn't happen in 5.20.2.

For instance, if I'm building C:\dir\text.tex, the build is emitted into C:\dir\c'\dir\. This happens when using Docker to build.

To Reproduce
Use 5.21.0 on Windows in VS Code 1.30.2. Build the project.

Expected behavior
I expect the build output to be placed in the same path as the .tex input, like in 5.20.2
