t/unit-tests: update clar to 206accb

Update clar from:

    - 1516124 (Merge pull request #97 from pks-t/pks-whitespace-fixes, 2024-08-15).

To:

    - 206accb (Merge pull request #108 from pks-t/pks-uclibc-without-wchar, 2024-10-21)

This update includes a bunch of fixes and improvements that we have
discussed in Git when initial support for clar was merged:

  - There is a ".editorconfig" file now.

  - Compatibility with Windows has been improved so that the clar
    compiles on this platform without an issue. This has been tested
    with Cygwin, MinGW and Microsoft Visual Studio.

  - clar now uses CMake. This does not impact us at all as we wire up
    the clar into our own build infrastructure anyway. This conversion
    was done such that we can easily run CI jobs against Windows.

  - Allocation failures are now checked for consistently.

  - We now define feature test macros in "clar.c", which fixes
    compilation on some platforms that didn't previously pull in
    non-standard functions like lstat(3p) or strdup(3p). This was
    reported by a user of OpenSUSE Leap.

  - We stop using `struct timezone`, which is undefined behaviour
    nowadays and results in a compilation error on some platforms.

  - We now use the combination of mktemp(3) and mkdir(3) on SunOS, same
    as we do on NonStop.

  - We now support uClibc without support for <wchar.h>.

The most important bits here are the improved platform compatibility
with Windows, OpenSUSE, SunOS and uClibc.
