iopodman.SearchImages: add ImageSearchFilter to Varlink API

Also add some argument checks to the Varlink function to avoid
referencing nil pointers, and complement the API.md descriptions.

The varlink endpoint can be tested via varlink CLI:

$ varlink call -m unix:/run/podman/io.podman/io.podman.SearchImages \
      '{"query": "ruby", "limit": 0, "tlsVerify": false, "filter": {}}'
