lavapipe/ci: Bump the number of tests per group

Due to the slow startup time of deqp-vk, the previous default of
500 tests per group caused the jobs to run up to twice as slowly
compared to using a higher number of tests per group.

Increase the number of tests per group for both subsets of the
deqp-runner suite, which allows decreasing the fraction.
