These two 'int' options:

ARCH_MMAP_RND_BITS_DEFAULT
ARCH_MMAP_RND_COMPAT_BITS_DEFAULT

are used directly as conditions for defaults. 'int' options should not be
used as conditions, because they will always evaluate to false.

Let's remove these options, because they are not used anywhere else.

This dead code was found by kconfirm, a static analysis tool for Kconfig.
