bitbake: toaster: allow pokydirname to be evaluated when all layers are local

Toaster depends on pokydirname for identifying the location of
the oe-init-build-env script (and there might be other purposes
in the future). The problem with current approach is that it
only checks/sets the variable with git based repos, whereas
toaster provides mechanisms to allow having layers that are all
locally available. The evaluation of the variable fails in such
scenarios, so use a more flexible mechanism in this case and
try to locate poky in the local layers as well, if not already
set.
