unix: add Sysv shared memory support
Implements proposed API from https://golang.org/issue/46084. I chose
`SysvShmDesc` since it's a clearer name than `SysvShm`. Initially supports Darwin and Linux.
Solaris support has a blocker (https://golang.org/issue/46084#issuecomment-836980018)
For golang/go#46084
