/snap/bin not on hook environment $PATH

[Stuart Bishop]

/snap/bin is not in the hook environment's $PATH, despite the snapd package being installed and having created /etc/profile.d/apps-bin-path.sh. The problem persists after a reboot, which indicates that the hook environment's $PATH is independent from the system $PATH. Either the hook environment should use the system path, or /snap/bin should be added to the hook environment $PATH.
