refactor(symfony-console): drop the unreachable process title surface

Command::setProcessTitle has no caller: neither Composer nor the ported
Symfony Console code sets a process title, so run()'s title branch could
never fire. The shim it called into was unimplementable anyway — PHP
rewrites its own argv block, which Rust hands out only as owned copies.
