check-code: always report when a file is skipped by "no-check-code"

Skipping an entire file generally from checking is an important event, so
report it always.
Do not tell the check name because skipping does not depend on it. Directly
skip the entire file instead of checking more patterns and skip again.

The pragma no-check-code was introduced by accident in the past. (Fixed in
e033a7d444ac and ee07f9d142c9.) This now is prevented because the files
to skip have to be listed in the test output of test-check-code-hg.t.

 New errors are not allowed. Warnings are strongly discouraged.
+(The writing "no-che?k-code" is for not skipping this file when checking.)
