Subject: [PATCH] ci-automation/sdk_bootstrap.sh: Allow omitting the optional
 parameters

The coreos/portage refs were allowed to be empty strings but the way
the function was run from Groovy the lack of quoting caused the empty
strings to be missing parameters.
Since the two parameters are meant to be optional, support omitting
them.
