lint: Verify if #:tests? is respected in the 'check' phase.

There have been a few patches to the mailing list lately
not respecting this, and this linter detects 630 package
definitions that could be modified to support the --without-tests
package transformation.

* guix/lint.scm
  (check-optional-tests): New linter.
  (%local-checkers)[optional-tests]: Add it.
* tests/lint.scm
  (package-with-phase-changes): New procedure.
  ("optional-tests: no check phase")
  ("optional-tests: check hase respects #:tests?")
  ("optional-tests: check phase ignores #:tests?")
  ("optional-tests: do not crash when #:phases is invalid")
  ("optional-tests: allow G-exps (no warning)")
  ("optional-tests: allow G-exps (warning)")
  ("optional-tests: complicated 'check' phase")
  ("optional-tests: 'check' phase is not first phase"): New tests.
