[PATCH v2] selftests/clone3: fix number of tests in ksft_set_plan

[Tobias Klauser]

Commit 515bddf0ec41 ("selftests/clone3: test clone3 with CLONE_NEWTIME")
added an additional test, so the number passed to ksft_set_plan needs to
be bumped accordingly.

Also use ksft_finished() to print results and exit. This will catch future
mismatches between ksft_set_plan() and the number of tests being run.
