[TEST] using builddir/android_build_result to build test

This PR includes changes in Android.mk to use
builddir/android_build_result. In order to use, soft link of
android_build_reuslt dir is necessary in upper dir (../)

ln -s ../../buildir/android_build_result ../nntrainer

Resolves:

**Self evaluation:**
1. Build test:	 [X]Passed [ ]Failed [ ]Skipped
2. Run test:	 [X]Passed [ ]Failed [ ]Skipped
