Install the proper requirements for pysaml2 in the trial test runners.

This installs xmlsec1 onto the Synapse trial test runners. This is required for pysaml2, so we need it for matrix-org/synapse#8800.

I wasn't sure if it made more sense to make a shell script in the Synapse repo and call that (like we do for old deps), but this seemed more tamper-proof.

Note that this gets installed for the old-deps build in matrix-org/synapse#8800.

I also wondered if there's a way to re-use steps or something for buildkite, but didn't see anything obvious.

you can use yaml entities if you want. the element-ios pipeline has examples iirc

Thanks! I made some changes based on that, not really sure how to test them though.

for future reference, there are some notes on testing pipelines at https://gitlab.matrix.org/new-vector/internal/-/wikis/BuildKite#testing-a-pipeline-locally.
