Vulkan test failures after pinning GLIBC versions to 2.2.5

[qiao-bo]

Taichi has a few math symbols exp, log, pow, log2 that will introduce dependencies on high GLIBC versions (such as 2.29), when building on systems such as Ubuntu 20.04. We found a way to pin these symbols back to an older version (2.2.5 GLIBC), which has been documented at #3426. Nevertheless, the method will introduce many Vulkan test failures such as:
