Remove fiat-crypto-legacy from CI

Motivations:
- We should have only maintained developments in our CI
- `make ci-fiat-crypto-legacy` takes about 15 mins before the first call
to `coqc`, making it unusable to work on overlays
- The coding style of this development is so fragile that adapting to
any change of behavior requires diffing gigabytes of Ltac traces.
@mattam82 and I have been blocked for 6 months this way, when working on
unifall.

I understand this development was meant to stress-test some components
like printing, but I think the trade-off is bad. We should rather come
up with specialized test suites for these components.
