redhat: configs: increase CONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE
Some really large instances do require a slightly increased pool size so kmemleak can track early system allocations before kmemleak_object entries can be allocated out of the system's slab caches. If there is not enough entries in the pre-allocated static pool, the facility is disabled at boot time and no futher tracking is done by kmemleak at system's runtime (see RHBZ#2008118).
This patch doubles the size of kmemleak's memory pool size which for now will allow enough room for proper kmemleak initialization for the large systems described at RHBZ#2008118. Kernel memory footprint for the kmemleak pool will increase from its current 7.17 mB to 14.34 mb.

@prarit since you filed a blocking thread for https://gitlab.com/redhat/centos-stream/src/kernel/centos- stream-9/-/merge_requests/245 due to "missing-in-ark" would you mind approving this MR and unblock the cs9 one?
Thanks in advance!

@hertonrk-rh @crecklin @arozansk @npache @esyr-rh @onestero @prarit We need review feedback on this config change.
