[libcxx] [test] Fix bucket_count() assumptions.

[STL_MSFT]

Summary

[libcxx] [test] Fix bucket_count() assumptions.

With a max_load_factor of 1.0, the only guarantee is that
bucket_count() >= size(). (Note: setting max_load_factor without
rehashing isn't supposed to affect this, because setting
max_load_factor is currently specified to be constant time.)
