From: Tomohiro Kusumi <tkusumi@xxxxxxxxxx>
lib/memalign.c not having dependency on fio.h enables it to be
a stand-alone library, which is useful for debugging purpose.
In fact, most of the files under lib/ directory do things this way.
(For lib/memalign.c, it was actually myself who introduced this
dependency as a part of changes made by 248c9436, so this commit
is partially reverting that)
