[release-branch.go1.20] cmd/go: fix tests for new builder environment

Fix two long tests that fail in the builders we're trying out:

- TestQueryImport was failing with:
  open /nonexist-gopath/pkg/sumdb/sum.golang.org/latest: no such file or directory
  which eventually turns out to be because it couldn't create
  /nonexist-gopath because it wasn't running as root. The test already
  uses a temporary GOPATH, but missed overriding a configuration
  variable set at init time.
- test_flags fails if the working directory has /x/ in it, which it now
  happens to.
