- Updates the SRC_URI to pull from the github project instead of debian
- Removes the need for the configure.ac patch since the github archive
still contains the webclient directory, no impact to built packages
- sha1.c patch now included on 0.9.11
- adds systemd dependency for distros building with systemd
- removes conf flag for libva since that support has been removed in
0.9.11
