Samuel Thibault 07dc0a64a3 realloc: Fix mmap non-mremap reallocation case [BZ #34697] ...

This case was missing copying SIZE_SZ bytes from the old allocation.

Fixes commit 614cfd0f8a
("malloc: Change mmap chunk layout"), which went into glibc 2.43.

Checked by Wilco Dijkstra <Wilco.Dijkstra@arm.com>

Resolves #34697.
