test: migrate stats/base/dists/logistic/mean to ULP-based assertions

[DivyanshuVortex]

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/logistic/mean from relative tolerance (EPS/delta/tol) assertions to ULP difference assertions using @stdlib/assert/is-almost-same-value.
• updates test/test.js. No other files are changed.
• removes the now-unused EPS and abs imports and the corresponding delta/tol variable declarations.
• verifies that the tests still pass identically under the 1 ULP bound. test.native.js was already using strict equality and required no changes.
