Improve portability of vector tests.
This test was assuming libcxx's 2x growth factor, which isn't guaranteed by the
Standard and isn't provided by MSVC (we use 1.5x). As a result the exact
capacity check fails. Marking the assertion as libcxx-specific is all we need,
and allows the rest of the test to succeed.
