ci: disable fast-fail on auto-fallible

The purpose of the auto-fallible job is to run builders that are likely to fail on CI without gating on them. Having fast-fail enabled there kinda defeats the purpose, as if one of them fails we can't monitor the outcome of the other ones.

This was prompted by the aarch64-gnu builder consistently failing due to a broken test, preventing us from seeing if the macOS spurious failure is fixed.
