Title: Emacs versus ctags

In addition to its etags executable, emacs now installs a ctags executable.
This stomps over exuberant-ctags, and makes it difficult to have emacs and
vim installed and use tags for both.

This follows what MacPorts does and removes bin/ctags and its manpage from
the build before linking. An option is provided for users who want to keep
`ctags` from emacs. Also, remove the conflict with ctags and add
a caveat to the formula about this whole issue.

This should fix #16826, #11089 and #8859.
