Fixup search

podman-remote search had some FIXMEs in tests that were failing.
So I reworked the search handler to use the local abi.  This
means the podman search and podman-remote search will use the
same functions.

While doing this, I noticed we were just outputing errors via
logrus.Error rather then returning them, which works ok for
podman but the messages get lost on podman-remote.  Changed
the code to actually return the error messages to the caller.

This allows us to turn on the remaining podman-remote FIXME
tests.
