script: backport-create-issue: optionally take list of issue numbers

Make the script optionally take a comma-separated list of issue numbers.
(Could be just one issue.)

Before this patch, backport-create-issue script insisted on looping over all
issues in Pending Backport status. This was cumbersome in cases when only
one issue (or a couple issues) needed to be processed.
