go/importer: disable TestForCompiler/LookupCustom for GOEXPERIMENT=unified
The TestForCompiler/LookupCustom test tries to read in the export data
for "math/big", but with a package path of "math/bigger" instead. This
has historically worked because the export data formats were designed
to not assume the package's own path, but I expect we can safely
remove support for this now.
However, since that would be a user-visible change, for now just
disable the test for GOEXPERIMENT=unified so we can land CL 393715. We
can revisit whether it's actually safe to break that go/importer use
case later.
Updates #51734.
