config: do not implicitly set coderepo.*.cgiturl

It's a needless waste of memory and this change reduces the
WwwCoderepo object size by over 25% with over 1K repos.
Using the following check:

  perl -MDevel::Size=total_size -I lib -MPublicInbox::WwwCoderepo -E \
  'say total_size(PublicInbox::WwwCoderepo->new(PublicInbox::Config->new))'

before: 1612515
 after: 1184385
