[PATCH] README: advertise lore.barebox.org instead of mail-archive.com

[Roland Hieber]

The archived messages at mail-archive.org only contain a few headers,
and getting git-am-able patch mails from their HTML pages is quirky at
best. Replace the link with the new lore instance, which has a number of
advantages, like raw message contents with full headers, cloneable git
archives, and interoperability with the b4 command line tool.
