[bug#28787] [PATCH] emacs-build-system: Improve command patching.

[Christopher Baines]

I came across a couple of improvements when looking at packaging
emacs-org-plus-contrib.

Christopher Baines (2):
  emacs-build-system: Handle missing programs when patching.
  emacs-build-system: Change how patch-el-files substitutes commands.
