Bug#887602: dia: Detect freetype via pkg-config

[Hugh McMaster <hugh.mcmaster@outlook.com>]

Package: dia
Version: 0.97.3+git20160930-7
Severity: important

Dear Maintainer,

The next version of libfreetype6-dev will *not* ship the 'freetype-config'
script.

Please use pkg-config to detect the freetype headers and libraries instead.

Thank you
