adjust wiki page

[Silvan Scherrer]

as createrepo and local repo doesn't need any pathweriter (when done proper), we need to adjust the wiki page.

the key in this is to have a local.repo file like the following:

[local]
name = My local repo
baseurl = file:e%3A/rpmbuild/localrepo
enabled=1

the %3A is the : character in a URI

then you can also create the localrepo with:

sh -c "createrepo e:/rpmbuild/localrepo"
