Bug#707955: TFTP fetch-url inserts superflous slash in remote file

[Mathias Bogaert <mathias.bogaert@gmail.com>]

Package: debian-installer-utils

Version: 1.95

The TFTP fetch-url method script inserts a slash in front of the remote file. This
breaks certain TFTP servers with 'access violation'. Since TFTP expects the
path to start at root, the slash is not necessary and can be removed.

so the line 
> remote_file="/$(echo $url | cut -d/ -f 4-)"

should be 
> remote_file="$(echo $url | cut -d/ -f 4-)"
