[igt-dev] [PATCH i-g-t] tests/i915/gem_ctx_create: lower active subtests timeout

[Kamil Konieczny]

Active subtests measure time for one cycle of context creation
and bufexec execution per engine and this is done until timeout
of 20 seconds expires. On old gpu gens there are low number of
engines so it runs in reasonable time, but on new ones it can
take as long as over 800s. Lower timeout to only 2s to keep it
low on CI. Below is example of dmesg output on new machine with
long 20 seconds timeout:
