netspeed: Use theme icons instead of embedded

This removes old icons included with the applet and instead uses icons from the current theme.

Known issues:
* Loopback interface does not have an icon, instead we use a "reload" icon to simulate it.
* PLIP/SLIP interfaces do not have proper icons, I managed to find an old PLIP icon in the hicolor theme and re-purposed it.
* Since not all icons have the same levels of scaling, I'm capping the size at 48px to keep all interfaces consistent.
* There are no icons for Wireless Quality, so I retained the existing ones for now.
