anv/meson: make sure tests link with -msse2

Without this, I get the following error when building the tests using
meson on i686:

---8<---
In file included from ../../../mesa/src/intel/vulkan/anv_private.h:46,
                 from ../../../mesa/src/intel/vulkan/tests/state_pool_no_free.c:26:

       __builtin_ia32_clflush(p);

    __builtin_ia32_mfence();

The errors are generated for each of these files:
- mesa/src/intel/vulkan/tests/state_pool_no_free.c
- mesa/src/intel/vulkan/tests/state_pool.c
- mesa/src/intel/vulkan/tests/block_pool_no_free.c
- mesa/src/intel/vulkan/tests/state_pool_free_list_only.c

This is obviously because gen_clflush.h contains code that uses
intrinsics that are only available with SSE3. Since the driver already
uses SSE3, it seems reasonable to add this to the tests as well.
