Closes #1819

Fix two issues with pciutils:

- pciutils would look in /usr/share/misc for pci.ids, but install it in
  /usr/share. This is because pciutils doesn't use a ./configure script,
  so we have to also provide the configuration (make) arguments when
  we run make install as well. Fix it by making it look into /usr/share
  as that's simpler to do, and is what upstream does.

- the update-pciids script would call wget with the --no-timestamping
  option, which isn't supported by busybox wget. Fix it by simply
  removing that option as it isn't really critical.
