benchmark-reverse: add file reads

Note: find currently complains like this:

 find: failed to read file names from file system at or below
 ‘/tmp/linux-3.0.reverse.mnt.vNI’: No such file or directory

I have analyzed this and it is caused by the non-stable inode numbers
that gocryptfs -reverse uses. Will be fixed in a later commit.
