hwdata: bump to version 0.308

The hwdata collection is hosted at GitHub now and provides additional
databases, besides pci.ids and usb.ids:

- Individual Address Block (IAB) and Organizationally Unique Identifier
  (OUI) databases, from IEEE Registration Authority
- PNP ID database (from Microsoft)

Install only pci.ids and usb.ids by default, to keep compatibility with
previous versions.

In the future we can make other packages (pciutils, lshw) use the common
files instead of installing their own copies, thus saving some storage
space.
