    gccrs: ast: Rename header guard
    
    The header guard did not match the file name anymore.
    
    gcc/rust/ChangeLog:
    
            * ast/rust-ast-collector.h (RUST_AST_TOKENSTREAM_H): Rename
            headerguard from RUST_AST_TOKENSTREAM_H ...
            (RUST_AST_COLLECTOR_H): ... to RUST_AST_COLLECTOR_H.
