Retry apt-get install for memory-leaks config

[p-datadog]

What does this PR do?

This configuration is frequently failing due to HTTP 503 error when installing valgrind. Retry the installation one time after a short break to see if this would make the configuration less flaky.

Motivation:
Repeated test failures

👍 I'm not sure if this will fix it, but it's cheap to try

Minor: Modern versions of apt don't need apt-get (they're mostly aliases)

Suggested change

	- run: sudo apt-get update && (sudo apt-get install -y valgrind || sleep 5 && sudo apt-get install -y valgrind) && valgrind --version
	- run: sudo apt update && (sudo apt install -y valgrind || sleep 5 && sudo apt install -y valgrind) && valgrind --version

While apt and apt-get do overlap in functionality, apt is not intended for script usage and makes fewer/no interface compatibility guarantees compared to underlying tools like apt-get (https://unix.stackexchange.com/questions/590699/should-i-use-apt-or-apt-get-in-shell-scripting, https://serverfault.com/questions/958003/how-to-disable-warning-apt-does-not-have-a-stable-cli-interface, https://manpages.ubuntu.com/manpages/xenial/man8/apt.8.html).
