t/unit-tests: update to 10e96bc

Update to 10e96bc (Merge pull request #127 from
pks-gitlab/pks-ci-improvements, 2025-09-22). This commit includes a
couple of changes:

  - The GitHub CI has been updated to include a 32 bit CI job.
    Furthermore, the jobs now compile with "-Werror" and more warnings
    enabled.

  - An issue was addressed where `uintptr_t` is not available on
    NonStop [1].

  - The clar selftests have been restructured so that it is now possible
    to add small test suites more readily. This was done to add tests
    for the above addressed issue, where we now use "%p" to print
    pointers in a platform dependent way.

  - An issue was addressed where the test output had a trailing
    whitespace with certain output formats, which caused whitespace
    issues in the test expectation files.
