syntax-check: do not enforce ChangeLog syntax

Our last conforming ChangeLog was removed from git in 2009 by:
commit 27b175b9a254d5dc4bbc1d6f198f58b287e516a2
    generate ChangeLog from git logs into distribution tarball

Ten years later, it reappeared in:
commit ce97c33a795dec053f1e85c65ecd924b8c6ec4ba
    maint: Stop generating ChangeLog from git
which does not have a single line complying to this syntax
check rule.

At some point between the two commits VC_LIST_EXCEPT gained
a default exception for ChangeLog and it did not seem to be
overriden anywhere.

Just remove the rule.
