Refactor the check added in 5476e1efde (fetch-pack: print and use
dangling .gitmodules, 2021-02-22) to make use of us now passing the
"msg_id" to the user defined "error_func". We can now compare against
the FSCK_MSG_GITMODULES_MISSING instead of parsing the generated
message.

Let's also replace register_found_gitmodules() with directly
manipulating the "gitmodules_found" member. A recent commit moved it
into "fsck_options" so we could do this here.

Add a fsck-cb.c file similar to parse-options-cb.c, the alternative
would be to either define this directly in fsck.c as a public API, or
to create some library shared by fetch-pack.c ad builtin/index-pack.

I expect that there won't be many of these fsck utility functions in
the future, so just having a single fsck-cb.c makes sense.

I'm not convinced that having a single cb function merits its
own file. But, if you expect this pattern to be expanded a
couple more times, then I would say it is worth it. Do you have
such plans?
