Fix up opengcs CI issues/remove ginkgo from Makefile

We're not using ginkgo for any of our tests anymore (that I can see) so for Makefile
test just swap to running every test in /internal/guest which comprises (mostly) all of the
Linux specific guest features.

This commit also adds linter tags to a couple things to fix up deadcode warnings as well as fixes
a casing mistake on the setSubreaper function in /internal/guest/runtime/runc/runc.go
