fix: 防止GetDumpResult将空字符串赋值给dumpResult

Created-by: denganliang
Commit-by: denganliang
Merged-by: openharmony_ci
Description: ## 修改说明

- 防止 GetDumpResult 将 malloc 分配但内容为空字符串的 buf 赋值给 dumpResult
- 根因：当 OHOS_GetMemLeakString malloc 分配了缓冲区但内容为空字符串时，原代码只判断 buf!=nullptr 就赋值
- 增加 *buf!=空字符 判断，与 buf!=nullptr 一起构成双重防御
