gnu: cgit: Don't build cgit's special 'git:src' input.

This special version of Git is only used within the build process of
cgit. We don't need to build it otherwise, so the package is removed
with this commit.

* gnu/packages/version-control.scm (cgit)[inputs]: Replace the git@2.10
package with an origin reference of the source code.
(git@2.10): Remove variable.
