This updates the FeatureSplit test sample to reflect the current
way of doing correct feature splits.
This is not final, as aapt2 will be gaining some improvements to
make access of private resources across feature splits valid by default.

This change allows the developer to add a base package for
which to build a feature split. The generated resource types
will begin after the base APK's defined types so as not
to collide or override resources.
Multiple features can be generated by first choosing an
arbitrary order for the features. Then for each feature,
the base APK and any preceding features are specified
with the --feature-of flags.
So with a base APK 'A' and features, 'B', and 'C',
'B' would be built with
aapt package [...] --feature-of A [...]
and 'C' would be built with
aapt package [...] --feature-of A --feature-of B [...]
