The previous code did not count the number of virtual processors across
physical processors on SunOS.

Can handle the following situations:

```
$ uname -a
SunOS solaris 5.11 11.4.0.15.0 i86pc i386 i86pc
$ psrinfo -p -v
The physical processor has 1 virtual processor (0)
  x86 (GenuineIntel 306D2 family 6 model 61 step 2 clock 3492 MHz)
        Intel Core Processor (Broadwell)
The physical processor has 1 virtual processor (1)
  x86 (GenuineIntel 306D2 family 6 model 61 step 2 clock 3492 MHz)
        Intel Core Processor (Broadwell)
The physical processor has 1 virtual processor (2)
  x86 (GenuineIntel 306D2 family 6 model 61 step 2 clock 3492 MHz)
        Intel Core Processor (Broadwell)
The physical processor has 1 virtual processor (3)
  x86 (GenuineIntel 306D2 family 6 model 61 step 2 clock 3492 MHz)
        Intel Core Processor (Broadwell)
```

```
