chmod o+x .ssh when creating hst-filemanager-key (#2755)

i habitually chmod my .ssh folders to 0700, that broke filemanager, wasted some time figuring out what the problem was, this will hopefully save someone else from having to figure out that the filemanager requires a minimum of o+x (interestingly it doesn't require o+r so i left it out)
