How would these two worms react to classical hardening tips such as PHP Safe mode and noexec /tmp ?

For this particular strain it would certainly help, but that is why there exists new variations. Certainly doing it to /tmp, /usr/tmp, /var/tmp could help, but it isn't 100% foolproof, and some don't even consider it security.

It only protects you from exploits that cannot just go;

source /tmp/rootkit.sh

or other, equivalent methods.

ie its only effective against directly executing files on those filesystems; you can still use other methods to run them.
