Tweak kernel patch needle to avoid raw patch files

Seems like the top '[patch]' link on kernel.org may now be a
raw patch file which the browser just displays, not a compressed
patch it offers to download. So tweak the needle so we should
click on the *bottom* link instead. openQA looks for matches
as close as possible to the location in the needle.
