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)
--- FAIL: TestDevices//dev/null_1:3 (0.00s)
dev_linux_test.go:45: for /dev/null Major(0x0) == 0, want 1

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.
