poky-init-build-env: Update for BASH 4 Bourne Shell semantics

It's no longer valid in bash 4 when invoked with Bourne Shell semantics to
return unless you're inside a sourced script or a function.  Doing so in
this context doesn't actually exit from the setup script.  This should
probably preserve the original intent.
