ci(cmakev2): run the buildv2 tests only if the buildv2 label is set

Currently, the buildv2 tests are initiated using the same patterns as
the tests for the current build system. This means that any change in
the current build system will also trigger the buildv2 tests. Initially,
it might be wise not to block the CI for changes in the current build
system in case there is an issue with buildv2. Therefore, let's
explicitly start the buildv2 tests only when the buildv2 label is set.
