runtime: Don't change test behaviour based on $CI or $KATA_DEV_MODE

go-test.sh changes behaviour based on both the $CI and $KATA_DEV_MODE
variables, but not in a way that makes a lot of sense.

If either one is set it uses the test_coverage path, instead of the
test_local path.  That collects coverage information, as the name
suggests, but it also means it runs the tests twice as root and
non-root, which is very non-obvious.

It's not clear what use case the test_local path is for at all.
Developer local builds will typically have $KATA_DEV_MODE set and CI
builds will have $CI set.  There's essentially no downside to running
coverage all the time - it has little impact on the test runtime.

In addition, if *both* $CI and $KATA_DEV_MODE are set, the script
refuses to run things as root, considering it "unsafe".  While having
both set might be unwise in a general sense, there's not really any
way running sudo can be any more unsafe than it is with either one
set.

So, simplify everything by just always running the test_coverage path.
This leaves the test_local path unused, so we can remove it entirely.
