package/freerdp: bump version

This version bump is needed to provide support for ffmpeg 3.0, added
Sep, 17th, 2015: https://github.com/FreeRDP/FreeRDP/pull/2895

Please note the we can not bump to a newer version of freerdp atm
because the next commit in the master branch

https://github.com/FreeRDP/FreeRDP/commit/8206ae440f905b123cb92c7abf8c861070ea8cd8

bumped the version number to 2.x which will provide freerdp2.pc instead
of freerdp.pc, this is incompatible with vlc atm:
