Don't treat git repos as non-existent when `ignore_git` is set
The new submodule handling depends on `is_git()` to be accurate to
decide whether it should handle submodules at all or not. Unfortunately,
`is_git()` treated "this directory does not have a git repository" and
"this repository should not be used for SHA/version/commit date info"
the same. This changes it to distinguish the two.
To clarify: ignore_get is set by default whenever channel == "dev", which it is by default whenever you're compiling locally. So basically everyone would hit this, not just people who had explicitly configured ignore_git.
Here's an example of an error this fixes:
```

I *believe* this regression was only introduced in rust-lang#87380, not rust-lang#82653. `@petrochenkov` can you check that this fixes the issue you encountered in rust-lang#82653 (comment) ?
