[aur-general] Remove `emacs-ocaml-mode`

[Sergei Lebedev]

While `emacs-ocaml-mode` [*] is part of the OCaml distribution it's not
included in the `ocaml` package (for reasons unknown) and can only be
installed from AUR. So, why remove?

* orphaned package; unsupported for more than a year
* can be installed from Marmalade repository via `package.el` [1]
* can be installed via `el-get` [2]
* everybody's using `tuareg-mode` [3] anyway :)

So, what do you guys think?
