gnu: emacs: Don't error on missing commands. 

This is a follow-up to commit 64557bc695.
Inputs lacking from emacs proper may not be present in emacs-minimal,
thus throwing an error on lookup.  This error is already anticipated in
the handling code.

* gnu/packages/emacs.scm (emacs)[patch-program-file-names]: Wrap
search-input-file in false-if-exception.
