Arnout Vandecappelle (Essensium/Mind) 66f40a7242 download/cvs: add a 10 minute timeout
Apparently, CVS servers can be deadlocked and in that case clients will
retry connecting to them indefinitely. Cfr.
http://autobuild.buildroot.net/results/23d/23d1034b33d0354de15de2ec4a8ccd0603e8db78/build-end.log
Apparently, the sf.net CVS server got in such a deadlock on 2018-05-18,
and almost 2 weeks later it is still not fixed.

Instead of just hanging, we should fall back on BR2_SECONDARY_SITE. To
achieve this, it's sufficient to add a timeout to the CVS command.

The timeout value is of course arbitrary. However, we can assume that
nobody will be putting large projects under CVS any more. So if the
download takes more than 5 minutes, it's probably broken. Let's put the
timeout at 10 minutes then.

Fixes:
