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.
