hyper-v: Tools: hv: Handle the case when the target file exists correctly

Bug Description

Hello,
Please see the attached patch, it contains a fix for hv_fcopy_daemon file-copy tool which better handles the error reporting if a file already exists on the guest VM.
Would this be included in the final release or as a later update for 14.04?

Thank you!
Chris

Hi Luis,
I've tried to use the -proposed branch, however it fails to find the new kernel.
