Windows: code quality improvement for --move and --remove options

When the --move or --remove options are used, ClamAV carefully traverses
the file path one layer at a time so as to avoid following a directory
that is a symlink or reparse point.
We do this for directories, but could also do it for files.
Only an admin should be able to create a reparse point for a file,
but it is better to be consistent.

Thank you to Maxim Suhanov for reporting this issue.
