Subject: [PATCH] libobs: Add pkgconfig support

Based on:

http://dailycommit.blogspot.com/2016/10/how-to-generate-pkg-config-file-with.html
https://people.freedesktop.org/~dbn/pkg-config-guide.html

Should allow third party plugins to find and use libobs more easily.

Closes obsproject/obs-studio#1467
