Add dep on fpc-srpm-macros.
    
    Note: I had to either bump the release and not the version, or use a
    non-integer version, in order to make sure that this package doesn't end
    up newer than the F24 version, which would happen after one more update
    which I do intend to make.
    
    Sorry.  The request to keep the version in that manner is simply not
    workable in the general case.
