LibJS: Avoid undefined static cast of negative values in to_u32
If the value we get after fmod in Value::to_u32 is negative, UBSAN
complains that -N is out of bounds for u32. An extra static cast to i64
makes it stop complaining. An alternative implementation could add 2^32
if the fmod'd value is negative. Caught by UBSAN and oss-fuzz.
