Subject: [PATCH] tests: zero-init ccmTag to satisfy clang-tidy

clang-tidy (all-c89, async-quic, intelasm) flagged `ccmTag[0] ^= 0x01` as a use
of an uninitialized value: the analyzer does not model wc_AesCcmEncrypt writing
the tag buffer. Zero-initialize ccmTag; the subsequent encrypt still overwrites
it before the tamper, so behavior is unchanged.
