support/scripts/generate-gitlab-ci-yml: allow multiple tests in one pipeline

The current Gitlab CI mechanism allows to trigger all tests in a CI
pipeline by pushing a branch named <something>-runtime-tests, or to
trigger a single test in a CI pipeline by pushing a branch name
<something>-tests.<name of test>.

However, there are cases where it is useful to run a suite of tests,
for example to run all tests in tests.init.test_busybox.

This commit makes that possible by extending the current semantic of
<something>-tests.<name of test> to not expect a complete test name,
but instead to accept all tests that starts with the given pattern.

This allows to do:

  git push gitlab HEAD:foobar-tests.init.test_busybox.TestInitSystemBusyboxRo

like it was the case before. But it now also allows to do:

  git push gitlab HEAD:foobar-tests.init.test_busybox

to run all Busybox tests.
