checkasm: float_dsp: Scale FLT/DBL_EPSILON sufficiently when comparing 

As the values generated by av_bmg_get can be arbitrarily large
(only the stddev is specified), we can't use a fixed tolerance.

This matches what was done for test_vector_dmul_scalar in
38f966b222.

This fixes the float_dsp checkasm test for some seeds, when built
with clang for mingw/x86_32.
