systemd: Don't clobber the system $PATH in the terminal
systemd: Don't clobber the system $PATH in the terminal

These days, the default `$PATH` is set via pam_env(8), not any more in
/etc/profile, and usually not in ~/.bashrc either. So let's not clobber
it by overwriting it to a static fixed value (which was also missing
at least /usr/local).

Fixes #8814
Closes #11212
