Add configs for files marked as `font/eot`

By default the configurations from this repository ensure that
`.eot` files are served with the `application/vnd.ms-fontobject`
media type, compressed, and with far future expires headers.
However, not all users use all the configurations provided by
this project, or in some cases, the headers are overwritten from
the level "beneath" Apache (e.g.: from `php`).

Looking at the results from the HTTP Archive¹ from 15.10.2014:

  +----+--------------------+---------------------------------+
  |    | number of requests |        media type               |
  +----+--------------------+---------------------------------+
  | 1  |            7406888 | image/jpeg                      |
  |    |                ... |                             ... |
* | 10 |             683558 | font/eot                        |
  |    |                ... |                             ... |
* | 17 |             176674 | application/vnd.ms-fontobject   |
  |    |                ... |                             ... |
  +----+--------------------+---------------------------------+

it's clear that the `font/eot` media type is used way more often
than the IANA registered² `application/vnd.ms-fontobject`.

Other incorrect/unofficial media types are also used, but their
usage is either wrong or low enough to not justify their addition.

  | 15 |                 86 | application/x-font-eot          |
  |    |                ... |                             ... |
  | 17 |                 44 | application/font-eot            |

Because of the things stated above, the changes from this
commit will ensure that Apache will serve anything labeled with
the `font/eot` compressed and with far future expires headers.
