Try a named GNU mirror before the redirector

[frangarcj]

Two hosts turned out to be too few, for a different reason from one being too few. ftpmirror.gnu.org is a redirector to whichever mirror is near, and the one it picked answered with an HTTP error:

-- Using src='https://ftpmirror.gnu.org/gnu/gdb/gdb-15.2.tar.xz'
   error: downloading ... failed
   status_code: 22
   status_string: "HTTP response code said error"

after which the fallback to ftp.gnu.org timed out the way it has all week.

mirrors.kernel.org goes first: it is the same host every time, so it can be seen to work rather than hoped about. The redirector stays behind it as the thing that keeps working when that host does not, and ftp.gnu.org stays last.

Checked — kernel.org returns gdb-15.2.tar.xz with the sha256 already pinned here:

mirrors.kernel.org   OK 83350ccd35b5b5a0
mirror.dogado.de     OK 83350ccd35b5b5a0
esperado                83350ccd35b5b5a0

The test now asks for three hosts, refuses ftp.gnu.org as the first, and requires it as the last.
