Subject: [PATCH] lib: fix boinc_file_exists() on Windows

The function is documented to check if anything exists at the given path. The client depends on this behavior. If the function checks only for regular files the client will fail to clean up slot directories before using them for another task.

Fix the function to match the documentation.
