fixed #17665: [android] Crash while launching on the devices only support OpenGL ES 2. (#17671)

* fixed #17665: [android] Crash while launching on the devices only support OpenGL ES 2.
Fixes that egl.eglCreateContext may return non-null but EGL10.EGL_NO_CONTEXT value.
It will cause create a EGL env with a EGL_NO_CONTEXT egl context which will cause crash.

* Don’t link with libGLESv1_CM.so
