/bin/sh shells cannot read /etc/profile.d/path.sh

* Description:
A script with header `#/bin/sh -l` or a user logging in with this shell will have a broken environment on ubuntu (22.04) as `/bin/sh` is a symlink to `dash` and `dash` cannot read the `bash` syntax in `/etc/profile.d/path.sh`

* Affected versions
PC-version: 3.*

Start by reproducing the login-shell behavior on Ubuntu 22.04 with /bin/sh and inspect /etc/profile.d/path.sh for the bash syntax that dash cannot read. Done means a /bin/sh -l script or user login receives a working environment without breaking the existing bash behavior.
