The defrag.exe tool which is used for executing the fstrim command
on Windows doesn't support retrim for OSes lower than Win8. This
commit handles this case and returns a suitable error.
Output of fstrim before this commit:
{"execute":"guest-fstrim"}
{"return": {"paths": [{"path": "C:\\", "error": "An invalid command line option
was specified. (0x89000008)"}, {"path": "F:\\", "error": "An invalid command
line option was specified. (0x89000008)"}, {"path": "S:\\", "error": "An
invalid command line option was specified. (0x89000008)"}]}}
