patch to add dependency

The deskutils/calibre port lacks a dependency on textproc/py-markdown.

Whet using the "Polish books" feature of calibre (enabled by adding it to
a toolbar or menu), the following error is shown:

calibre 4.6  embedded-python: False is64bit: True
FreeBSD-12.1-STABLE-amd64-64bit-ELF FreeBSD ('64bit', 'ELF')

ImportError: No module named markdown

So the markdown module is missing. Adding a dependency to textproc/py-markdown
fixes that.
