TST: seed the noisy accelerometer and gyroscope fixtures

Following @zuorenchen's review note on #13, seed the remaining noisy sensor
fixtures (noisy_rotated_accelerometer, noisy_rotated_gyroscope) the same way
noisy_barometer already is, so the whole sensor suite is deterministic instead
of relying on statistical tolerance bounds. Uses the seed argument added in #13.
