gnu: git: Invert inheritance relationship.

It's simpler to add features on top of a minimal variant than to remove them,
and helps avoiding mistakenly changing git-minimal, which has many dependents.

* gnu/packages/version-control.scm (git-minimal): Move above git and severe
inheritance.  Remove input label.  Repatriate most fields from...
(git): ... here.  Define as package/inherit to inherit from git-minimal.
Extend minimal values instead of overriding them whole.
