I was about to suggest that you might ask the Flycheck maintainer to
provide a function that can be used instead of the macro
flycheck-define-checker, but I see that it's pretty much already the
case: just use flycheck-define-command-checker.

Another option, is to compile that file and then you can do

    (eval-when-compile (require 'flycheck))
    (with-eval-after-load 'flycheck
      (flycheck-define-checker
        …))

it also works if you don't byte-compile, except that the
with-eval-after-load becomes ineffective.
