bitbake: cooker: Change to consistent prefile/postfile handling

Currently the original prefile and postfile passed when starting bitbake
server are 'sticky'. With the new memory resident model this doesn't make
sense as the server the system is started with isn't special.

This patch changes the code so the prefile/postfile are used if specified
on the commandline and not used otherwise. This makes the behaviour much
more predictable and expected and as an added bonus simplifies the code.
