package/flutter-gallery: clean up install_target_cmds
Remove and create the kernel_blob.bin file in the flutter_assets directory:
When Flutter compiles the source code, it creates the kernel_blob.bin file,
a Dart Kernel Bytecode of the application.
If kernel_blob.bin exists inside the flutter_assets directory, then the
application source code can be extracted with nothing more than apktool.
Not only is this a security risk, it's also redundant and a waste of space.
Removing the kernel_blob.bin file generated for flutter-gallery saves 86M!
Because this package is a reference package, and some applications may check
if the kernel_blob.bin file exists, we also touch a blank kernel_blob.bin
file.
Do not use relative symlinks:
Users may install their applications in any arbitaryt location, not
necessarily in the /usr/share/flutter/${package_name} directory. Because
flutter-gallery is a reference application, using exact symlinks to
icudtl.dat and libflutter_engine.so is preferable.
