[PATCH 2/3] gitlab-ci.yml: Add a job to build EDK2 firmware binaries

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Add a GitLab job to build the EDK2 firmware binaries.
This job is only built when the roms/edk2/ submodule is updated,
when a git-ref starts with 'edk2' or when the last commit contains
'EDK2'.

GitLab CI generates an artifacts.zip file containing the firmware
binaries.

With edk2-stable201905, the job took 40 minutes 26 seconds,
the artifacts.zip takes 10MiB.
