    bin/df: fix build with MOUNT_CHAR_DEVS defined
    
    When resolving conflicts due to the unmergewd commit that removed the
    code previously made conditional on MOUNT_CHAR_DEVS, I failed to see
    that MOUNT needed to be defined in the Makefile and that the include
    of mntopts.h was still required for that case.
    
    Fix the build by adding back the missing definitions to the Makefile.
