Replace libpci with new parser.

libpci was only used to find a marketing string for a device.
This patch looks for a pci.ids on disk and parses it to extract the
same string, using 'Device xxxx' as the fallback on file i/o error
or missing data from the text file. Tested by checking every vendor/
device pair against the values returned from libpci.
