[bug#38754] [PATCH 1/4] lint: Add a requires-store? field to the checker record.

[Christopher Baines <mail@cbaines.net>]

This can then be used to mark checkers that require a store connection, which
will enable passing a connection in, avoiding the overhead of establishing a
connection inside the check function when it's run for lots of different
packages.

* guix/lint.scm (<lint-checker>): Add requires-store? to the record type.
