Reason for reverting: this is failing on presubmits of prs that make
engine changes, presumably due to some missing gradle configuration to
handle that special case in resolving the engine binaries.

This change reverts the following previous change:
Fixes https://github.com/flutter/flutter/issues/169165.

`build_android_host_app_with_module_aar` was unfortunately not depending
on the module as an aar, but as source (something we have a different
test for, and something that you would not expect given the name of the
test 🤦 )
