alsa-info: provide DMI system sku

Browse source 
The system sku is used in SOF machine drivers to set specific quirks,
expose it in alsa-info to help support users. Example on a SoundWire
enabled device:

cat /sys/class/dmi/id/product_sku
0A32
dmidecode -s system-sku-number
0A32

Add a variable and expose the results of both methods.

Note that the dmidecode support is very recent and might not yet be
available in all distros:
