[release-branch.go1.18] internal/fuzz: fix TestUnmarshalMarshal on MIPS
Previous value used in the float32 roundtrip used float32(math.NaN())-1
which caused the quiet/signal bit to flip, which seemed to break the
test on MIPS platforms. Instead switch to using float32(math.NaN())+1,
which preserves the bit and makes the test happy.
Possibly related to #37455
Fixes #51258
