dnn-layer-mathbinary-test: Fix tests for cases with extra intermediate precision This fixes tests on 32 bit x86 mingw with clang, which uses x87 fpu by default. In this setup, while the get_expected function is declared to return float, the compiler is (especially given the optimization flags set) free to keep the intermediate values (in this case, the return value from the inlined function) in higher precision. This results in the situation where 7.28 (which actually, as a float, ends up as 7.2800002098), multiplied by 100, is 728.000000 when really forced into a 32 bit float, but 728.000021 when kept with higher intermediate precision. For the multiplication case, a more suitable epsilon would e.g. be 2*FLT_EPSILON*fabs(expected_output), but just increase the current hardcoded threshold for now.
