github-ci: add workflow_dispatch

A workflow dispatch allows us to manually a trigger a workflow with
arguments. This dispatch allows us to use the "gh" cli command to
trigger a workflow run with our libhtp/su/sv branch and repo variables
set. For example:

  gh run builds.yml -f SV_REPO=jasonish/suricata-verify -f SV_BRANCH=pr/10
