meta-ibm: Add sample build invocations

Display sample build invocations when sourcing oe-init-build-env.

These are only the most commonly used combinations of
distro/machine/image and not an exhaustive list of all supported
configurations.  Rather the purpose of displaying these is to help
bitbake newcomers quickly initiate a build without having to set DISTRO
and MACHINE in local.conf or wonder which image recipe to bake.
