[PATCH] setup: fix FTP behavior on timeout

[Igor Pechtchanski]

Hi,

I noticed this problem when trying to do a fresh install -- if selecting
packages takes too long, ftp mirrors will timeout, and setup will not
reconnect, causing the failure.  This patch fixes that.

As usual, the ChangeLog is below.
