scripts: lint: Handle store connections for lint checkers.
Rather than individual checkers opening up a connection to the store for each package to check, if any checker requires a store connection, open a connection and pass it to all checkers that would use it. This makes running the derivation checker much faster for multiple packages. * guix/scripts/lint.scm (run-checkers): Add a #:store argument, and pass the store to checkers if they require a store connection. (guix-lint): Establish a store connection if any checker requires one, and pass it through to run-checkers.
