[CI] Skip EETQ tests while package is broken with latest transformers (#34854)
* CI Skip EETQ tests while package is broken
EETQ tries to import the shard_checkpoint function from transformers but
the function has been removed. Therefore, trying to use EETQ currently
results in an import error. This fix results in EETQ tests being skipped
if there is an import error.
The issue has been reported to EETQ:
https://github.com/NetEase-FuXi/EETQ/issues/34
* Raise helpful error when trying to use eetq
* Forget to raise the error in else clause
