linux-firmware-rpidistro: Add cyfmac43455-sdio.bin symlink to minimal

Browse Source 
According to the README on rpi-distro firmware-nonfree [1] this symlink
needs to exists.

Fixes,

```
[    6.794584] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.bin failed with error -2
```

There are previous reported stability issues with 802.11r [2] and
choosing minimal removes this support and indirectly fixes the issues.
