/proc/<pid>/maps is incorrect

[csweichel]

Bug description

The /proc/<pid>/maps file is incorrect. It's unclear what causes this.
When running a Docker container in Gitpod, /proc/<pid>/maps is correct.

This is a possible cause of #5064

Possibly relevant issues:

• https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1843018
• Process.MainModule.FileName incorrect with kernel 5.0.0-27-generic (causing MSBuild to be broken) dotnet/runtime#30774

Steps to reproduce

cat /proc/self/maps

contains paths that don't really exist or make sense in the workspace.

Expected behavior

It should show the proper maps.
