[PATCH-for-6.1 v2] gitlab-ci: Extract OpenSBI job rules and fix 'when' condition

[PATCH-for-6.1 v2] gitlab-ci: Extract OpenSBI job rules and fix 'when' condition

[Philippe Mathieu-Daudé]

First, all jobs depending on 'docker-opensbi' job must use at most
all the rules that triggers it. The simplest way to ensure that is
to always use the same rules. Extract all the rules to a reusable
section, and include this section (with the 'extends' keyword) in
both 'docker-opensbi' and 'build-opensbi' jobs.

Second, jobs depending on another should not use the 'when: always'
condition, because if a dependency failed we should not keep running
jobs depending on it. The correct condition is 'when: on_success'.

The problems were introduced in commit c6fc0fc1a71 ("gitlab-ci.yml:
Add jobs to build OpenSBI firmware binaries"), but were revealed in
commit 91e9c47e50a ("docker: OpenSBI build job depends on OpenSBI
container").

This fix is similar to the one used with the EDK2 firmware job in
commit ac0595cf6b3 ("gitlab-ci: Extract EDK2 job rules to reusable
section").
