Fix unstable::dynamic_lib::test::test_loading_cosine on android

[yichoi]

Update Bug

test_loading_cosine is being ignored on android. This issue exists to remind that it should be fixed.

This is probably related to: #10356

Old Report

To enable test on android bot #9120

and

test/run-pass/linkage-visibility.rs

It looks to me that this issue is related with #10356

Triage bump. Keeping because it's referenced in the source code. Updated bug report.

Triage: this test is still disabled, and relevant issues still seem to be open. I don't have an android toolchain to test with further.

Triage: no changes since my last comment.
