Populate hiddenapi whitelist.

This list of packages is derived from all packages in the tree that do not
specify LOCAL_SDK_VERSION in their Android.mk. It was done by:

1.  Modifying biuld/core/package_internal.mk to output a warning for all
    packages that do not specify LOCAL_SDK_VERSION, including some
    metadata about the target.

2.  Parsing the output fom the build, then filtering out those that specify
    a test certificate, or with LOCAL_MODULE_TAGS := tests, that depend
    on android.test.runner or whose name includes "Test"

3.  Look up the java package name of each & build the list from these.

Test: N/A, this change is a no-op while all system apps are excluded
from the checks.
