Fix cross-version upgrade tests.
TestUpgradeXversion knows how to make the main regression database's
references to pg_regress.so be version-independent. But it doesn't
do that for plperl's database, so that the C function added by
commit b7e3a52a8 is causing cross-version upgrade test failures.
Path of least resistance is to just drop the function at the end
of the new test.
In <= v14, also take the opportunity to clean up the generated
test files.
