Tomas Vondra 4d916dd876 Stabilize test of BRIN parallel create

The test for parallel create of BRIN indexes added by commit 8225c2fd40
happens to be unstable - a background transaction (e.g. auto-analyze)
may hold back global xmin for the initial VACUUM / CREATE INDEX. If the
cleanup happens before the next CREATE INDEX, the indexes will not be
exactly the same.

This is the same issue as e2933a6e11, so fix it the same way by making
the table TEMPORARY, which uses an up-to-date cutoff xmin that is not
held back by other processes.

Reported by Alexander Lakhin, who also suggested the fix.
