'declare' linter does not obey --strict option

[joshbax189]

E.g. the following is the same with and without --strict

> eask lint declare --strict
`js-comint.el` with check-declare
js-comint.el:148:Warning (check-declare): said ‘nvm--find-exact-version-for’ was defined in .eask/31.0.50/elpa/nvm-20240921.1901/nvm.el: arglist mismatch


js-comint.el:148:Warning (check-declare): said ‘nvm--find-exact-version-for’ was defined in .eask/31.0.50/elpa/nvm-20240921.1901/nvm.el: arglist mismatch

`test-js-comint.el` with check-declare
No issues found

(Total of 2 files have checked)

Expect that the command exits with non-zero status but it exits with 0.

Also, notice that the warning is repeated.

Compare to the output of the checkdoc linter

> eask lint checkdoc --strict
`js-comint.el` with checkdoc (0.6.2)
No issues found

`test-js-comint.el` with checkdoc (0.6.2)
test-js-comint.el:0: The first line should be of the form: ";;; package --- Summary"
test-js-comint.el:0: You should have a section marked ";;; Commentary:"
test-js-comint.el:7: You should have a section marked ";;; Code:"
test-js-comint.el:137: The footer should be: (provide ’test-js-comint)\n;;; test-js-comint.el ends here
test-js-comint.el:8: Argument ‘regex’ should appear (as REGEX) in the doc string
test-js-comint.el:43: First line is not a complete sentence

(Total of 2 files have checked)

This exits with status 1 and all are marked as errors.

This is in version 0.10.1 of Eask
