oui-update: Explicitly sort OUI list and strip trailing whitespaces
It looks like http://standards-oui.ieee.org/oui.txt is no longer sorted
by OUI, so do in manually when creating oui.conf. Also, it looks like
the file has been converted to use CRLF line endings, so strip those as
well (and any other trailing whitespaces in the vendor name).
