drm/lima: increase default job timeout to 10s

The previous 500ms default timeout was fairly optimistic and could be
hit by real world applications. Many distributions targeting devices
with a Mali-4xx already bumped this timeout to a higher limit.
We can be generous here with a high value as 10s since this should
mostly catch buggy jobs like infinite loop shaders, and these don't
seem to happen very often in real applications.
