Copy imported APKs to output filename

android_app_import and android_test_import modules with processed: true
and skip_preprocessed_apk_checks are used directly from the source tree.
If the source file name doesn t match the module name and the file is
used as test data it can result in the wrong filename being used.  Copy
the source file to an output file with the correct name first.
