lshw: use data files provided by hwdata

lshw is seldomly released, so its data files become easily
outdated. Instead, this commit makes use of the data files provided by
hwdata. This is easily possible because lshw looks for the files in
several directories, including /usr/share/hwdata, where the hwdata
collection is installed.

We remove the entire /usr/share/lshw directory, where the not very
up-to-date data files where installed. Four files were installed
there: pci.ids, usb.ids (which are now provided by hwdata), manuf.txt
and oui.txt (which are not used at run time).

[Thomas:
 - rework commit log
 - replace patch by a simple removal of the /usr/share/lshw directory
 - add "runtime" comment in Config.in for the BR2_PACKAGE_LSHW
   dependency]
