Enable build dir outside of the poky directory

You need to first set up the build directory by sourcing the poky build script,
after that builds can be run in that directory so long as bitbake is in $PATH
removing the need to source the init script for each build.

i.e:
$ . poky-init-build-env ~/my-build
$ bitbake some-image
<<later, in a different shell>>
$ cd ~/my-build
$ export PATH=/path/to/bitbake/bin:$PATH
$ bitbake an-image

This patch also removes use of OEROOT in recipes, etc.
