    gccrs: nr2.0: Fix test self-path2.rs
    
    gcc/rust/ChangeLog:
    
            * resolve/rust-ast-resolve-path.cc
            (ResolvePath::resolve_path): Adjust the error message for a lower
            self segment in the middle of a path.
            * resolve/rust-ast-resolve-type.cc
            (ResolveRelativeTypePath::go): Likewise.
    
    gcc/testsuite/ChangeLog:
    
            * rust/compile/nr2/exclude: Remove self-path2.rs
            * rust/compile/self-path2.rs: Adjust expected errors.
