[Buildroot] [PATCH] wiringpi: New package

[Renaud AUBIN <root@renaud.io>]

Enable Raspberry Pi GPIO access through the WiringPi library.

Git http backend is not enabled on the official repo. There is no
official release tarball. As a consequence, this packaging uses an
unofficial repo hosted on github.
