Subject: [PATCH] Specify explicit library (not package) name for rustc_lexer

Hopefully fixes:

```
   Compiling rustc-ap-syntax v540.0.0
error[E0432]: unresolved import `rustc_lexer`
 --> /home/simon/.cargo/registry/src/github.spider-man.dpdns.org-1ecc6299db9ec823/rustc-ap-syntax-540.0.0/parse/lexer/mod.rs:8:5
  |
8 | use rustc_lexer::Base;
  |     ^^^^^^^^^^^ use of undeclared type or module `rustc_lexer`
```

For a dependency declared on `rustc-ap-rustc_lexer`, when trying to update rustfmt
