Jae Shin c13c0ea4b0 Remove path prefix within VNDK snapshot zip 
Remove 'android-vndk-snapshot' path prefix when creating VNDK
snapshot zip with soong_zip. The path prefix makes it cumbersome
to unzip and install the snapshots to prebuilts/vndk/v{version}.

Test: development/vndk/snapshot/build.sh &&
python development/vndk/snapshot/update.py
