Disable tests using injection points in installcheck

The 'gin' test injections faults to GIN index build. If another test
running concurrently in the same cluster also tries to create a GIN
index, it will hit the fault, too.

To fix, disable tests using injection points when running against an
existing cluster. A better long-term solution would be to make the
injection points scoped to the database or process, but this will do
for now.
