unit-test: meson: Use clang-tidy-fix

In meson 1.3.0 `clang-tidy-fix` target is added if `.clang-tidy` file
exists. This could be used to run clang-tidy with the fixes applied to
the source code.

Change the unit-test script to use `clang-tidy-fix` for meson projects.

Tested: Manually verify in a meson proejct that the `clang-tidy` check
        fixes the code if issues are found.
