eclass/tests: dot-a: add another strip vs index testcase

This is in addition to 44699664fa7aba134c327acb38c40851e0813ff4 and
1b826e95ac66bf54e532bb155261f4a39419efa9. It's an explicit, simple version
of the original testcase Markus gave on the bug (just with --strip-unneeded
instead of --strip-debug/-d).
