    wic: Add option to not change fstab

    Create an option to wic doesn't change fstab file, the final
    fstab file will be same that in rootfs and wic doesn't update
    file, e.g adding a new mount point.

    Users can control the fstab file content in base-files recipe.
    This is useful if you want to only create an partition but not
    add fstab mount point or add new mount point using label e.g:

    LABEL=recovery /recovery auto defaults 0  1

This change is useful to avoid duplicate entries on final image
fstab, and system will not mount partitions that doesn't exist.
