device: fix device major/minor

Current gvisor doesn't give devices a right major and minor number.

When testing golang supporting of gvisor, I run the test case below:

```
$ docker run -ti --runtime runsc golang:1.12.1 bash -c "cd /usr/local/go/src && ./run.bash "
```

And it reports some errors, one of them is:

"--- FAIL: TestDevices (0.00s)

        dev_linux_test.go:51: for /dev/urandom Mkdev(1, 9) == 0x109, want 0x0
"

So I think we'd better assign to them correct major/minor numbers following linux spec.
