fix(uu/cat): remove unnecessary semicolon after match statement in write_nonprint_to_end

Removed a trailing semicolon following the match arms in the `write_nonprint_to_end` function, which was likely causing a compiler warning or style issue in Rust. This ensures cleaner code without altering functionality.
