Executer: Fix link error for division.

ACPICA should not use 64-bit division directly. This triggers the following
build error on Linux i386 kernel builds:
  drivers/built-in.o: In function `acpi_ex_do_debug_object':
  (.text+0x4e1a4): undefined reference to `__udivdi3'

Since the following 2 statements are equivalent as 0x03FFFFFF masking
ensures lower bits of num/12 are kept, thus valid bits of num/10 should
have all be kept:
valid bits are remained:
 (UINT32) (num64 / 10) & 0x03FFFFFF;
 ((UINT32) num64 / 10) & 0x03FFFFFF;
This patch fixes this using the latter form statement to avoid 64-bit
division.
