[1/3] elf: Record main program constructor/destructor in ordering tests

Previously, the ordering was not capture in the test output.  Adjust
expected test output accordingly.  Note that after commit 6985865bc3a
("elf: Always call destructors in reverse constructor order
(bug 30785)"), the main program destructors in tst-bz28937 run last
(which is bug XXX).

Thanks, fixed locally.

Do we need to fill in bug XXX?

OK. Adjust testing with "." for main executable.
