Revert "lib/os/heap: introduce option to force big heap mode"

This reverts commit b6b6d39bb6.

With both commit 4690b8d5ec ("libc/minimal: fix malloc() allocated
memory alignment") and commit c822e0abbd ("libc/minimal: fix
realloc() allocated memory alignment") in place, there is no longer
a need for enforcing the big heap mode on every allocations.

help
The sys_heap allocator by default returns pointers to blocks
which are guaranteed to be aligned to the pointer size.
By enabling the "big chunks" mode, the returned blocks are
guaranteed to be 8 byte aligned, also on 32-bit platforms.
If this option is enabled, the "big chunks" mode will always
be used by sys_heap.
