poky-env-internal: Allow the environment variable POKYCONF to provide the basis for the working "conf" directory.

By using the POKYCONF variable, a meta layer can provide the basic setup for files to
be used during a build.  This is similar to the default values stored in the main meta
tree, .../meta/conf/local.conf.sample, etc
