[PATCH 3/4] powerpc: qemu-ppce500_defconfig: increase malloc area to default 4 MiB

qemu-ppce500 was the only PowerPC board with a 1 MiB malloc area, while
other boards range from 16 to 64 MiB and the Kconfig default is 4 MiB.

The small heap caused the talloc stress test to run out of memory
(the test randomly allocates up to 1024 buffers of 1-4096 bytes).
Drop the explicit CONFIG_MALLOC_SIZE override to use the default.
