RFR: 8356047: [macos] jpackage produces confusing post- and pre- installation PKG scripts [v2]

[Alexander Matveev]

> - Removed all code from pre- and post- installation PKG scripts.
> - This code is not needed and PKG should create destination folder and set correct permissions.
> - If for some reason it is not happens, permissions issues should be fixed when jpackage prepares application bundle. PKG should keep all permissions unchanged when packaging and installing bundle.
> - pre- and post- installation PKG scripts are kept as empty scripts, so user can override them if needed.
> - `INSTALL_LOCATION` and `APP_LOCATION` substitution is removed, since `$1` argument in scripts is same as `INSTALL_LOCATION`.
> - I think code in these scripts are some legacy leftovers.
