Re: [Libguestfs] [PATCH virt-v2v] -it ssh: Double quote ssh command which tests remote file exists

Double quoting was removed in commit e2af12ba69c4463bb73d30db63290a887cdd41eb ("input: -i vmx: Remove support for openssh scp < 8.8", Nov 2021). However it should only have been removed from scp commands, not for this ssh command where it is still required.
