cmd/go: pass down testing gccgo in TestScript

This permits TestScript to work when gccgo is not installed.
Previous testing was using a previously installed gccgo, not the newly
built one.

This revealed that the testing of whether an internal package is
permitted was incorrect for standard library packages, since the
uninstalled gccgo can see internal packages in the uninstalled libgo.
Fix the internal package tests.

This permitted removing a couple of gccgo-specific changes in the
testsuite.
