Emanuele f67e221738 test(libc): check that the macOS guest arena keeps free space beside host regions ...

The four guest_arena tests still pass with the mach_vm_region walk
disabled, because TryReserve marks every 1 GiB chunk it cannot reserve
as occupied. guest_arena_gap reads the host map before the arena
reserves its range and requires a fixed guest mapping in free space
that shares a chunk with a host region to be accepted.

The debt entry also records that on macOS 27.0.1 (M4 Pro) the
unmappable range starts at 0xF_C000_0000.
