pinky: tool unsupported on OpenBSD
- utmpx not supported on OpenBSD
- add src/uu/pinky/src/platform directory and platform/mod.rs for conditional compilation
according to target_os
- platform/openbsd.rs: implementation on OpenBSD (unsupported tool)
- platform/unix.rs: implementation on other OS
- src/uu/pinky/src/pinky.rs: use platform module for uucore::main function
