ci/turnip: Extend the full-vk-run job timeouts.

Between adding features and increased test coverage, we're hitting the
1-hour job limit.  !13441 tried to increase the full run timeout for LAVA,
but by having not bumped the gitlab-ci timeout value it ended up just
letting the job keep running in LAVA after gitlab had given up on it.
