Build with -ftrivial-auto-var-init=zero

[z3ntu]

According to upstream[0] there are several cases of variables or struct members not being initialized, but since they're using -ftrivial-auto-var-init=zero to build the code, those will be zero-initialized by the compiler already.

The CMake files should add this flag also to not hit bugs[1] due to uninitialized variables.

I assume we should be able to add these lines here https://github.com/nmeum/android-tools/blob/master/vendor/CMakeLists.txt#L18

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -ftrivial-auto-var-init=zero")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -ftrivial-auto-var-init=zero")

Let me know if I should open a pull request with this or if you have other suggestions.

Please wait until the pending pull request is being resolved.

I don't see how it could conflict with #132 though, is there some concern there?
