devel/universal-ctags conflicts with emacs and update, commit request

[Derek Schrock]

Could someone take a look at https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223076

This fixes an issue with devel/universal-ctags conflicting with emacs'
ctags binary by prefixing unviersal-ctags with a "u" and updates
devel/universal-ctags to a new commit.

Also, what's the best way for myself or the bug submitter to catch the
attention of a committer if/when a patch is attach to Bugzilla?  Should
the bug submitter change the title of the bug prefixing with [patch] and
a URL update if a Phabricator review was created or is a mailing list
request like the following best?
