[PATCH 16/21] drm/i915/selftests: reduce num_guc_ids

[Matthew Auld]

If we have small BAR for LMEM, then the number of contexts that we can
keep pinned at any one time is limited, since each requires some CPU
visible memory for the context image and ring. Empirically, reducing
num_guc_ids down to 64 seems to be small enough with 256M BAR on DG1.
