- Add openobex's unusual pkgconfig to pkgconfig path
- Prepend dbus_libs pkgconfig to pkgconfig path, as otherwise the dbus-daemon pkgconfig wins,
  as it has the same name (dbus-1.pc), which doesn't provide all the dbus headers that are needed
- Apply the included patch to obex-data-server which lets it build against current openobex
