match libdvdcss version with libdvdread since it depends on
matching libdvdcss API
o No meaningless overhead since libdvdread automatically uses
libdvdcss whether the port has knowledge of it or not. Besides,
all ports using libdvdread list libdvdcss as a dependency as well
(exception made to xine_d5d_plugin but an updated version will)
o Also, it's a 22K overhead
o Furthermore, all ports depending on libdvdread SHOULD depend on
libdvdcss for obvious reasons
