Fix the mac build of e2fsprogs

Android builds for MacOS 10.5.  The new version version of e2fsprogs requires
posix_memalign(), which was added in MacOS 10.6.  Since MacOS doesn't provide
memalign() either, the only option is to use valloc().  This patch was inspired
by a patch to e2fsprogs that came from the macports port of e2fsprogs.
