Pass app visible packages data directory info to zygote

These information are needed to isolate apps data directory.

Only normal app zygote forks require these info, as
- system process - Does not need data isolation
- app zygote - It's for generating isolated process, so don't need
access apps data.
webview zygote - Similar to isolated process, don't need to access
apps data.

Test: Able to see the package name, volume uuid, and inode nuber
for each visible package in zygote
