[PATCHv2 1/6] gitweb: channel image in rss feed

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

Define the channel image for the rss feed when the logo or favicon are
defined, preferring the former to the latter. As suggested in the RSS
2.0 specifications, the image's title and link as set to the same as the
channel's.
