openmp冲突引起crash

[ljdang]

两个动态库test1.so和test2.so，其中test1.so链接了ncnn动态库，test2.so链接了opencv-mobile静态库，单独使用时，功能都是正常。在同一个app中引用，加载的时候会出现openmp冲突问题。

context | 编译/运行环境 | バックグラウンド

Android NDK21
ncnn-20230223-android-vulkan-shared
opencv-mobile-4.8.1-android

替换成opencv-mobile-4.6.0-android版本不包含openmp，但是编译的时候需要自己链接openmp，不然编译不过
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fopenmp -static-openmp")

替换成原生opencv，test2.so链接opencv动态库，这时候，一起加载是正常的
