checkasm: af_afir: Use a dynamic tolerance depending on values As the values generated by av_bmg_get can be arbitrarily large (only the stddev is specified), we can't use a fixed tolerance. Calculate a dynamic tolerance (like in float_dsp from 38f966b2222db), based on the individual steps of the calculation. This fixes running this test with certain seeds, when built with clang for mingw/x86_32.
