x86/boot: Fix randconfig build error due to MEMORY_HOTREMOVE

When building randconfigs, one of the failures is:

  ld: arch/x86/boot/compressed/kaslr.o: in function `choose_random_location':
  kaslr.c:(.text+0xbf7): undefined reference to `count_immovable_mem_regions'
  ld: kaslr.c:(.text+0xcbe): undefined reference to `immovable_mem'
  make[2]: *** [arch/x86/boot/compressed/vmlinux] Error 1

because CONFIG_ACPI is not enabled in this particular .config but
CONFIG_MEMORY_HOTREMOVE is and count_immovable_mem_regions() is
unresolvable because it is defined in compressed/acpi.c which is the
compilation unit that depends on CONFIG_ACPI.

Add CONFIG_ACPI to the explicit dependencies for MEMORY_HOTREMOVE.
