MAVLink FTP: Update implementation according to updates specs

Browse Source 
The MAVLink specs for CreateFile in MAVLink FTP were updated on Dec 23, 2020 (today) with a behavior change to truncate a file if it already existed, following the UNIX standard behavior: https://pubs.opengroup.org/onlinepubs/9699919799/functions/creat.html. This change is tracking that spec change. While it is a functional change, the limited usage of the FTP protocol and the fact that implementations should not rely on error states to determine wether to truncate a file or not makes this a viable change.
