Indeed, installer plugins run in a separate (from the Installer) process on
Catalina, thus all the application structure has been changed.
Here is the undocumented way of getting the package path from the plug-in that
works on Catalina as well,

but understand the limitations of the approach

It doesn't work on 10.10.5 either.
The PACKAGE_PATH environment variable is set when running the pre and
post-installation scripts.
The environment variables that are set and visible from a plugin are
the ones that are listed in install.log (or in the Log window of
Installer.app).
