Subject: [PATCH] zeroize: add `#[ignore]` to flaky CString test

This test relies on UB and is flaking out in certain cases:

https://github.com/RustCrypto/utils/issues/774

It's unclear if the test failure indicates a genuine bug in the
implementation, or is the result of a test with UB.

However, in the meantime it shouldn't block users who would just like
the test suite to run reliably.
