exec: Fix prototype of phys_mem_set_alloc and related functions 

phys_mem_alloc and its assigned values qemu_anon_ram_alloc and
legacy_s390_alloc must have identical argument lists.

legacy_s390_alloc uses the size parameter to call mmap, so size_t is
good enough for all of them.

This patch fixes compiler errors on i686 Linux hosts:

  CC    alpha-softmmu/exec.o
exec.c:752:51: error:
 initialization from incompatible pointer type [-Werror]
exec.c: In function 'qemu_ram_alloc_from_ptr':

exec.c: In function 'qemu_ram_remap':
exec.c:1283:21: error:
 comparison of distinct pointer types lacks a cast [-Werror]
