Revert "gdb/testsuite: add KFAILs to gdb.reverse/step-reverse.exp"

This reverts commit 476410b3bca1389ee69e9c8fa18aaee16793a56d.

One of Simon's recent commits (2a740b3ba4c9f39c86dd75e0914ee00942cab471)
changed the way recording a remote target works and fixed the underlying
issue of the bug, so the KFails can be removed from the test.
