Subject: [PATCH] test: migrate `stats/base/dists/uniform/stdev` to ULP-based
 assertions

Replace the relative tolerance (`EPS`-based) assertions in `test/test.js`
and `test/test.native.js` with ULP difference assertions using
`@stdlib/assert/is-almost-same-value`.

The maximum observed ULP difference across the full 1000-value Julia
fixture set is 1 for both the JavaScript and the native C implementation,
so both files use a bound of 1 ULP.
