poky-init-build-env: Enable all POSIX shells
Update the script so that it will work in more then just bash. If bash is not used, it will assume the PWD is the Poky location. (This is because BASH_SOURCE is a bash-ism, and equivalent functionality is not available in other shells). This has been verified with dash (see comment in the code), ksh, zsh and of course bash.
