.gitlab-ci.d: Split build and test in cross build job templates

.gitlab-ci.d: Split build and test in cross build job templates

In the native_build_job_template we have separate steps in the script
for the build and the test steps.  This is helpful because then
gitlab will give separate timestamps in the log view for each, and
you can see how long it took to compile vs how long to test.  In the
templates in crossbuild-template.yml, however, we do both the build
and test in a single 'make' invocation, and so we don't get the
separate timing information.

Split the build and test, in the same way we do in the native build
template.

This will also give us a place to separate out how parallel we want
to do the build by default from how parallel we want to do the tests
by default, which might be helpful in future.
