gem5: fix --gem5-readfile

Browse Source 
Was completely broken due to confusion between --gem5-readfile and a common
variable with the same name which referred to the file path... OMG.

Conclusion: no one has ever used this tutorial!

Improve ./gem5.sh documentation.

Also fix ./gem5-bench-dhrystone.
