RESUME_FROM: clarify what ftp uploads do

When doing uploads with FTP, the resume position is where in the local/source

file libcurl should try to resume the upload from and it will then append the

source file to the remote target file.

Pass a curl_off_t as parameter. It contains the offset in number of bytes that
