Tweak suggestion span for outer attr and point at item following invalid inner attr
After:
```
error: `unix_sigpipe` attribute cannot be used at crate level
--> $DIR/unix_sigpipe-crate.rs:2:1
|
LL | #![unix_sigpipe = "inherit"]
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
LL |
LL | fn main() {}
| ------------ the inner attribute doesn't annotate this function
|
help: perhaps you meant to use an outer attribute
|
LL - #![unix_sigpipe = "inherit"]
LL + #[unix_sigpipe = "inherit"]
|
```
Before:
```
