security/libgcrypt: Fix build on hardware lacking SM4-EVEXHEADmain

The failure comes from cipher/sm4-intel-avx512-amd64.S, which uses the
EVEX-encoded (zmm) SM4 instructions. The base system assembler only
knows the VEX/ymm forms, and configure's SM4 probe only tests those, so
the AVX512 implementation is assembled anyway and breaks.

This patch extends the probe with the zmm forms, so the Intel SM4
assembly is disabled automatically where the assembler lacks SM4-EVEX.
GFNI-based SM4 and all other AVX512 code remain enabled, and the check
heals itself once LLVM gains these instructions.
