fix search output limit

close https://bugzilla.redhat.com/show_bug.cgi?id=1732280
From the bug Podman search returns 25 results even when limit option `--limit` is larger than 25(maxQueries). They want Podman to return `--limit` results.

This PR fixes the number of output result.
if --limit not set, return MIN(maxQueries, len(res))
if --limit is set, return MIN(option, len(res))
