Skip auto-gen rro packages for path requirements.

The way these packages are currently added to the build is via
modifications in product makefiles inheriting from mainline_system,
but with have the side effect of changing the REQURIED modules for
the source of the auto-gen RRO package.

Whitelist auto-generated RRO packages from the path requirement checks
for now.
