fix(#5362): Cannot run `make test-smoke` on arm64 out of the box

[tdiesler]

I made a simple change to test_support that adds the the missing -t builder.platforms trait when on arm64 and not given already, as well as a simple wrapper script that sets the required CAMEL_K_TEST_* envars when on arm64

Create sub-shell

 ./script/e2e_env.sh shell
 $ go test -v -tags=integration ./e2e/common/languages/java_test.go

Run a command in this environment

 ./script/e2e_env.sh run go test -v -tags=integration ./e2e/common/languages/java_test.go
