Exclude the PIC key package_info from shared memory

The PIC key package_info is being sniffed as a sysprop outside of the
cache infrastructure, so it cannot be moved into shared memory yet.
This change excludes that one key from shared memory (when the feature
flag is enabled).

This is expected to be temporary until a mechanism is provided to
clients to sniff nonce changes in controlled way.

This change also corrects the bug numbers in the trunk stable flags
related to this effort.

Tested by booting an image with the flag enabled and verifying that
the package_info cache key exists as a system property, but other
system_server cache keys are not properties.
