[202505] [ci]: Changes to unblock swss pipeline tests (#3806)

Part of the changes in #3664. test_mirror.py fixes have already bee backported to 202505 via #3700

What I did

Allow partially succeeded swss common artifacts to be pulled. Otherwise, swss builds in 202505 will fail with the error ##[error]No builds currently exist in the pipeline definition supplied. when pulling swss-common artifacts
Why I did it

To fix docker vs build and test on 202505 branch
How I verified it

By ensuring that pipeline runs are successful on 202505 swss branch
