send-email: handle Windows paths for display just like we do for processing

In git-send-email.perl, here are two checks to determine if
$smtp_server is an absolute path (so it'll be treated as a mailer) or
not (so it'll be treated as a hostname).  The one that handles actual
mail processing has been taught to recognize Windows pathnames by
commit 33b2e81.

The other check is just to tell the user what happened, so it's far
less important, but the current state is that we will still claim to
the user that c:/foo/bar is a server. =)  This makes the second check
consistent with the first.
