intel/ci: Drop timeout overrides for pre-merge jobs

LAVA jobs already have a global 1h timeout in GitLab. This exists because
GitLab jobs must start before we can determine whether a device is
available for testing.

Jobs themselves do not normally run that long, most of the delay comes
from waiting in the LAVA queue.

Dropping these overrides for pre-merge jobs fixes cases where the LAVA
job isn't picked up in time.
