[Libosinfo] [libosinfo] Allow to use system pci.ids/usb.ids files

[Christophe Fergeau]

Most distros already ship copies of pci.ids/usb.ids. This commit
allows to make use of these rather than the ones shipped with
libosinfo. This is achieved through the use of
--with-usb-ids-path and --with-pci-ids-path configure flags.
