Andrey Konovalov bd9d9624b7 lib/stackdepot: adjust DEPOT_POOLS_CAP for KMSAN 
KMSAN is frequently used in fuzzing scenarios and thus saves a lot of
stack traces.  As KMSAN does not support evicting stack traces from the
stack depot, the stack depot capacity might be reached quickly with large
stack records.

Adjust the maximum number of stack depot pools for this case.

The average size of a stack trace saved into the stack depot is ~16
frames.  Thus, adjust the maximum pools number accordingly to keep the
maximum number of stack traces that can be saved into the stack depot
similar to the one that was allowed before the stack trace eviction
changes.
