ci: use LLVM libcxx 21.1.5
What changed, and why it matters
This commit simply updates the version of a testing tool (LLVM's libc++) used in automated continuous integration builds from 21.1.1 to 21.1.5. It does not change any Bitcoin Core code that runs on user machines, and there is no indication it fixes a security issue.
No action needed. Treat as a routine CI maintenance change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff changes one line in ci/test/01_base_install.sh, updating the git clone branch for the LLVM project from llvmorg-21.1.1 to llvmorg-21.1.5 when building an instrumented C++ standard library for CI. This is a routine dependency bump in the CI infrastructure.
