fix: speed up ci

[maxday]

Follow-up on the integration tests. AL1, Amazon Corretto, and Alpine were already set to -DmultiArch=false since we now have a dedicated matrix job per architecture. This PR adds the same flag to the distributions where it was missing (AL2, Ubuntu, and Debian), roughly halving the integration test time for those distributions. No coverage is lost, as all architectures are still tested through the matrix.
