ci: Update TF-M version to eb8ff0d

Update TF-M version to keep up with code development. Fixes and new
features have been introduced on both sides, using a more recent
TF-M version helps to detect regression.

Update script to also pull in the version of tf-m-tests that suggested
by the main repo, since this is now required to build the test image.
