[bug#68180] [PATCH v3 1/4] gnu: emacs: Patch awk, find, sed and sh commands.

[Maxim Cournoyer <maxim.cournoyer@gmail.com>]

Before this change, using Emacs in a pure environment, e.g. 'guix shell --pure
emacs', would cause problems such as:

  jka-compr-insert-file-contents: Uncompression program ‘sh’ not found

And other problems were found requiring the other tools.

* gnu/packages/emacs.scm (emacs-minimal) [arguments]: Extend the
patch-program-file-names phase.
[inputs]: Add findutils, gawk and sed.
