[PATCH v5 19/29] CI: move "env" definitions into ci/lib.sh

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Have the GitHub CI jobs use the "ci/lib".sh as a source of truth for
environment variables that affect their builds and tests. This brings
them in line with the rest of the jobs, and make it easier to see the
entire CI configuration per jobname at a glance.

To do this we need to add a ci/lib.sh "step" to the remaining jobs
that didn't have it added in preceding commits.

The Makefile parameters are luckily all accepted via the environment,
so we can export these instead of adding them to MAKEFLAGS.

Let's also use the documented GIT_CONIFG_* mechanism for setting
config instead of the internal GIT_CONFIG_PARAMETERS variable. This
adjusts code added in 889cacb6897 (ci: configure GitHub Actions for
CI/PR, 2020-04-11), we could probably use the GIT_AUTHOR_NAME etc, but
let's keep setting this via config, just with the documented
mechanism.

By setting "ARTIFACTS_DIRECTORY=artifacts" once we don't need to
repeat it in various places, let's get it from the environment
instead.

Finally, the "DEVELOPER: 1" was only needed by the "sparse" job, which
wasn't using "ci/lib.sh" (and which sets DEVELOPER=1). Let's instead
have the "sparse" job use the "ci/lib.sh" and remove DEVELOPER=1 from
".github/workflows/main.yml".

This substantially speeds up the "sparse" job, since it'll now pick up
the "--jobs" setting in MAKEFLAGS that we use everywhere else. Before
it ran in around 4m30s, now in around 2m30s.
