[lldb/Util] Use md5 instead of python's hash function. 

Because of the way the Python hash function works, it's not guaranteed
to be the same. This was causing a lot of reproducers to be generated
for the same tests, even though the CWD or arguments didn't change.
Switching to an MD5 hash should fix that.
