Move some test fixtures to go

moves ensure-frozen-images to go
moves ensure-syscall-test to go
moves ensure-nnp-test to go
moves ensure-httpserver to go

Also makes some of the fixtures load only for the required tests.
This makes sure that fixtures that won't be needed for a test run such as
`make TESTFLAGS='-check.f Swarm' test-integration-cli` (for example)
aren't loaded... like the syscall tests.
