[PATCH] scripts/checkpatch: Improve the check for authors mangled by the mailing list

[Thomas Huth]

There were recently some patches on the list which had their "From:"
line mangled like this:

 From: qemu_oss--- via <qemu-devel@nongnu.org>

Since our test in the checkpatch.pl script did not trigger here, the
patches finally also ended up in a pull request, with the wrong author
set. So let's improve the regular expression to also complain on
these new patterns, too.

I would probably generalize the pattern even a bit more:

		if ($line =~ /^(Author|From): .*<qemu-devel\@nongnu.org>/) {

Because mailman's precise sender-rewrite prefix changed couple times. But for 
now the change above will do as well of course.
