gnu: emacs-magit: Substitute git executable path.

Magit has a strong dependency on Git so it should directly reference the
git executable rather than expect it to be available in the profile or
environment.

This also fixes a build failure in emacs-forge.

* gnu/packages/emacs-xyz.scm (emacs-magit)[arguments]<#:phases>: Substitute
git path in the ‘magit-git-executable’ variable.
