fix(nixos/git-server): Correctly specify the section from path length

Cgit effectively splits the repo path on '/' and then takes
`section-from-path` segments, which form the section. A negative value
here results in cgit traversing the path from left to right instead of
right to left. Beware that cgit only sets the section, if the path
contains `section-from-path` or more slashes in it (thus rendering this
setting defunct with the previous value of 1000).

There seems to be no way to tell cgit to always use all components up-to
the second to last for the section name, thus requiring all projects
that need a longer than 1 section length to set the `cgit.section`
git config variable via gitolite.
