Fix unportable shell-script syntax in pg_upgrade's test.sh.
I discovered the hard way that on some old shells, the locution FOO="" unset FOO does not behave the same as FOO=""; unset FOO and in fact leaves FOO set to an empty string. test.sh was inconsistently spelling it different ways on adjacent lines. This got broken relatively recently, in commit c737a2e56, so the lack of field reports to date doesn't represent a lot of evidence that the problem is rare.
