[remote] import --signature-policy /no/such/file: runs happily

[edsantiago]

$ bin/podman-remote run --name foo alpine true
$ bin/podman-remote export -o /tmp/podman-foo.tar foo
$ bin/podman-remote import --signature-policy /no/such/file /tmp/podman-foo.tar

Expected:

Error: open /no/such/file: no such file or directory

--signature-policy shoud not even be valid for podman-remote.
