[op] Replace syscall package usage with golang.org/x/sys/unix in runsc/.

The syscall package has been deprecated in favor of golang.org/x/sys.

Note that syscall is still used in some places because the following don't seem
to have an equivalent in unix package:
- syscall.SysProcIDMap
- syscall.Credential

Updates #214
