gnu: emacs-magit: Simplify package.

These changes are based on emacs-forge package. As all magit related packages
share the same structure, let’s build them similarly.

* gnu/packages/emacs-xyz.scm (emacs-magit): Simplify package.
[arguments]<#:exclude>: Remove unexisting excludes.
<#:phases>: Remove unnecessary configure-git phase.  Remove all unnecessary
replace phases.  Add new chdir-lisp phase to operate from lisp dir.  No need
to make files writable.  Group all emacs-substitute-variables, and remove
relative path.
<#:test-command>: Consider updated makefile path.
