lib: Move bitmap.o from lib-y to obj-y.

[Paul Mundt <lethal@linux-sh.org>]

mac80211 has a reference to __bitmap_empty() via bitmap_empty().
In lib/bitmap.c this is flagged with an EXPORT_SYMBOL(), but
this is ultimately ineffective due to bitmap.o being linked in
lib-y, resulting in:

ERROR: "__bitmap_empty" [net/mac80211/mac80211.ko] undefined!

Moving bitmap.o to obj-y fixes this up.
