Ignore -Wstringop-overread warning for SHA1Transform() on GCC 12 (#11538)
Fix compile warning for SHA1Transform() method under alpine with GCC 12. Warning: ``` In function 'SHA1Update', inlined from 'SHA1Final' at sha1.c:187:9: sha1.c:144:13: error: 'SHA1Transform' reading 64 bytes from a region of size 0 [-Werror=stringop-overread] 144 | SHA1Transform(context->state, &data[i]); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sha1.c:144:13: note: referencing argument 2 of type 'const unsigned char[64]' sha1.c: In function 'SHA1Final': sha1.c:56:6: note: in a call to function 'SHA1Transform' 56 | void SHA1Transform(uint32_t state[5], const unsigned char buffer[64]) | ^~~~~~~~~~~~~ ``` This warning is a false positive because it has been determined in the loop judgment that there must be 64 chars after position `i` ```c for ( ; i + 63 < len; i += 64) { SHA1Transform(context->state, &data[i]); } ``` Reference: https://github.com/libevent/libevent/commit/e1d7d3e40a7fd50348d849046fbfd9bf976e643c
