nit: do not use syscall package

Browse Source 
In many places (not all of them though) we can use `unix.`
instead of `syscall.` as these are indentical.

In particular, x/sys/unix defines:

```go
type Signal = syscall.Signal
type Errno = syscall.Errno
type SysProcAttr = syscall.SysProcAttr

const ENODEV      = syscall.Errno(0x13)
```

and unix.Exec() calls syscall.Exec().
