fsdev: fix virtfs-proxy-helper cwd

Since chroot() doesn't change the current directory, it is indeed a good
practice to chdir() to the target directory and then then chroot(), or
to chroot() to the target directory and then chdir("/").

The current code does neither of them actually. Let's go for the latter.

This doesn't fix any security issue since all of this takes place before
the helper begins to process requests.
