Clarify non-x86 hardware info sources for snmpd (#12253)

* Clarify non-x86 hardware info sources for snmpd

* Clarify that ARM platforms use device tree, not SMBIOS _(maybe consider a wrapper script for this too?)_
* Non-GPS based systems can also provide lat & lon, such as Galileo or Beidou
* Clarify that Distro means Distribution

* Update SNMP-Configuration-Examples.md

/sys/devices/virtual/dmi/id/product_serial` in the crontab for root or
equivalent.
Non-x86 or SMBIOS-based systems, such as ARM-based Raspberry Pi units should
query device tree locations for this metadata, for example:
```
extend hardware '/bin/cat /sys/firmware/devicetree/base/model'
extend serial '/bin/cat /sys/firmware/devicetree/base/serial-number'
```
The LibreNMS server include a copy of this example here:
