app-editors/emacs: Fix multiple command injection vulnerabilities

This fixes command injection vulnerabilities in etags (CVE-2022-48337),
ruby-mode (CVE-2022-48338), and htmlfontify (CVE-2022-48339) for Emacs
slots 25, 26, 27, and 28.

Note that Emacs 25 and 26 are not affected by the ruby-mode
vulnerability because function ruby-find-library-file did not yet
exist (and there is no call to the gem command in ruby-mode.el).

Emacs 18 is not affected by either of them: It doesn't have ruby-mode
and htmlfontify, and we no longer install the ctags and etags binaries.
