    mount.nfs: Fix the sloppy option processing
    
    The new mount API broke how the sloppy option is parsed.
    So the option processing needs to be moved up in
    the mount.nfs command.
    
    The option needs to be the first option in the string
    that is passed into the kernel with the -s mount(8)
    and/or the -o sloppy is used.
    
    Commit 92b664ef fixed the process of the -s flag
    and this version fixes the -o sloppy processing
    as well works when libmount-mount is and is not
    enabled plus cleans up the mount options passed
    to the kernel.
