    Fix too small hostname buffer in bootparamd
    
    This fixes the following warning from clang 14:
    
    usr.sbin/bootparamd/bootparamd/bootparamd.c:204:32: error: 'fscanf' may
    overflow; destination buffer in argument 3 has size 255, but the
    corresponding specifier may require size 256 [-Werror,-Wfortify-source]
    
    The MAX_MACHINE_NAME macro indicates the maximum number of bytes in a
    machine name, but it does not include the NUL terminator required for
    scanf.
    
    MFC after:       3 days
    
    (cherry picked from commit d310bf3867b4168e57365196c3a31797c0538097)
