[autofill] Add missing form_structure_browsertest cases to iOS

Tests 148 through 151 were not included in the test case bundle (copy
step for dependendent data) in the iOS build, so these tests were not
being run on that platform.

This CL adds the input and output files to the unit_tests_bundle_data.
