    [aqbanking] Again use aqbanking version number for new function instead of cmake_symbol_check
    
    This reverts commit adae341d, "Use cmake_symbol_check to test for
    AB_Banking_RuntimeConfig_SetCharValue". We received multiple reports
    that the cmake check fails and the behaviour unexpectedly does not use
    the new function. As this is completely counter-intuitive as long as the
    new-enough aqbanking version are there, we better just stick
    to the aqbanking version numbers, especially because this function is used
    only in exactly one place here.
