[sanitizer_common][test] Always skip select allocator tests on SPARC V9 (#100530)

Two allocator tests `FAIL` on Linux/sparc64:
```
  SanitizerCommon-Unit :: ./Sanitizer-sparcv9-Test/SanitizerCommon/CombinedAllocator32Compact
  SanitizerCommon-Unit :: ./Sanitizer-sparcv9-Test/SanitizerCommon/SizeClassAllocator32Iteration
```
The failure mode is the same on Solaris/sparcv9, where those tests are
already disabled since 0f69cbe.
Therefore, this patch skips them on SPARC in general.

Tested on `sparc64-unknown-linux-gnu` and `sparcv9-sun-solaris2.11`.

(cherry picked from commit 3d14912)
