tests/float/float_parse: Allow test to run on 32-bit archs.

Browse Source 
Printing of uPy floats can differ by the floating-point precision on
different architectures (eg 64-bit vs 32-bit x86), so it's not possible to
using printing of floats in some parts of this test.  Instead we can just
check for equivalence with what is known to be the correct answer.
