[bug#48272] [PATCH] gnu: emacs-ledger-mode: Simplify build

[Morgan.J.Smith@outlook.com]

From: Morgan Smith <Morgan.J.Smith@outlook.com>

* gnu/packages/finance.scm (emacs-ledger-mode)
[build-system]: Use emacs-build-system instead of cmake
[arguments]:
- Remove modules and imported-modules.
- Move patch-path phase to after unpack so that the substitution actually
causes a change.
- Remove generate-autoload phase as that's built into the build system.
- Remove patch-site-dir as that only affected cmake things
[native-inputs]: Remove emacs-minimal
