Buildfarm member Narwhal: Python 2.5/8.1

New buildfarm member Narwhal is failing the PL regression tests for 
Python on REL8_1_STABLE. This appears to be because it's running Python 
2.5 (the causes being a deprecated module - whrandom - and some changed 
messages).

The former problem was fixed by Peter, and the latter by Tom but both 
only for 8.2+`- any reason this wasn't backported to 8.1? I couldn't 
find anything in the archives.
