wcfs: Setup basic logging for warnings/errors to go to stderr when invoked as e.g. `wcfs serve`

If we do not setup logging explicitly, it will print only

    No handlers could be found for logger "wcfs"

instead of emitting useful details in before e.g.

    RuntimeError: fuse_unmount /dev/shm/wcfs/<X>: failed: fusermount: failed to unmount /dev/shm/wcfs/<X>: Device or resource busy
    (more details logged)

-> Fix it.
