util/spkmodem-recv: don't use modulus on decode

it's slow on older compilers/systems that don't optimise.

instead, we branch (cheaper) and just do an above or
equal comparison), resetting appropriately or subtracting.

should yield an actually useful performance gain, on older
systems. a bit theoretical on modern systems, which optimise
well (modern compilers will produce assembly code much like
what the new C code is doing)
