58532f36d0 Update the testcase for MDEV-10330 
Instead of restart_mysqld.inc, truncate the P_S tables that are used
by the test. We don't want to query some irrelevant data.

a4dc9561ee MDEV-10330: main.show_explain_ps fails sporadically in buildbot 
The reason is that selecting from events_waits_history_long creates
a race condition: it can happen that SHOW EXPLAIN thread was kicked
off CPU exactly after posting a SHOW EXPLAIN request and then it wont
need to wait.

It doesn't seem to make sense to add more waits to stabilize the testcase.
Let's instead make a check that SHOW EXPLAIN statement has a
"stage/sql/show explain" stage.
