Support #pragma once
"#pragma once" acts like a multiple-inclusion guard affecting the entire file,
without an associated preprocessor symbol.
This allows use of sparse on projects that rely on #pragma once without
also using an ifndef-based multiple-inclusion guard, such as systemd;
without this change, sparse will get into an include loop.
