- The mode of testdir was changed to allow reading from other users/groups.
- The java multipart test now uploads the file into an app writable dir.
- The build directory was made readable for other users.
- The python environment test now uses the HOME env var instead of PWD
because the latter is not set by the root shell (/bin/sh) by default.
- The node `node_modules` directory now is copied into the `testdir` instead
of using symlinks.
When using "credential: true", the new namespace starts with a completely
empty uid and gid ranges. Then, any setuid/setgid/setgroups calls using ids
not properly mapped with uidmap and gidmap fields return EINVAL, meaning
the id is not valid inside the new namespace.
