Dont ICE when encountering indeterminate paths in rustdoc

[compiler-errors]

Not sure if we can avoid having indeterminate paths due to the way that we handle globs (see test), so just suppress the ICE here.

Fixes #100241

Note: The UI test I provided is literally wrong, I don't know how to make a rustdoc test distinguish ICE (bad) and regular fail (good), since we don't have any sort of granularity in failure mode except for // should-fail, which triggers any time rustdoc fails at all.

Perhaps someone knows how to fix this at the compiletest level?

PathResult::Indeterminate shouldn't appear there, there must be some other underlying issue.

It would be better to find where this PathResult::Indeterminate is created and fix the underlying issue instead of hiding it.

Yup, I can do that. The minimized example is pretty small, so doesn't seem too impossible.
