Running tests with a user name with numbers fails tests

[Benedikt Ziemons]

Running python ulwgl_test.py as a user without a pure alphabetic name (e.g. user3) does not currently work.
I tried pinpointing the issue and it seems to be related to regular expressions like these: https://github.com/Open-Wine-Components/ULWGL-launcher/blob/33bd82851aba4106851523cd952511ead0057da2/ulwgl_test.py#L906
In general, the actual user home directory should not be of any concern to successfully running tests and this regex doesn't suffice for all cases of user home directories (numbers in user name, having the home directory outside of /home, …).

The tests give the following output:
