Fix explain regression test failure.

Commit 9d701e6 caused the regression test for EXPLAIN to fail on the buildfarm member prion. This happened because of instability of test output, i.e., in text format, whether "Planning:" line is output varies depending on the system state. This commit updated the regression test so that it ignores that "Planning:" line to produce more stable test output and get rid of the test failure. Back-patch to v13.
