[PATCH 3/3] memblock tests: fix undefined reference to `BIT'

[Wei Yang]

commit 772dd0342727 ("mm: enumerate all gfp flags") define gfp flags
with the help of BIT, while gfp_types.h doesn't include header file for
the definition. This through an error on building memblock tests.

Let's include linux/bits.h to fix it.
