Subject: [PATCH] rngd: update modalias to match cpu type

It looks like the cpu type part of modalias might have changed, my
systems (4.4.20 and 4.7.2) show something like the following:

```
cpu:type:x86,ven0000fam0006mod003F:feature:,0000,0001,0002,0003,0004,0005,0006,0007,0008,0009,000B,000C,000D,000E,000F,0010,0011,0013,0017,0018,0019,001A,001C,002B,0034,003B,003D,0068,006F,0070,0072,0074,0075,0076,007D,0080,0081,0089,008C,008D,0091,0093,0094,0095,0096,0097,0098,0099,009A,009B,009C,009D,009E,009F,00C0,00C5,0120,0123,0125,0127,0128,0129,012A,0140
```

Update the rngd modalias rule to match this so udev properly has
systemd start rngd.
