test: migrate stats/base/dists/laplace/skewness to ULP-based assertions

[aryan7071]

Resolves a part of #11352

Description

What is the purpose of this pull request?

This pull request:

• migrates the test suite for stats/base/dists/laplace/skewness from relative tolerance (EPS/delta/tol) assertions to ULP difference assertions using @stdlib/assert/is-almost-same-value.
• updates test/test.js and test/test.native.js. No other files are changed.
• removes the now-unused EPS and abs imports and the corresponding delta/tol variable declarations from each file.
• the ULP bound was verified directly against the fixture data using a script that computes the actual ULP distance between computed and expected values for every input. Verified minimum: 1 (all fixture values matched exactly on both JS and native, confirmed by running the verification against both implementations).
