[FFmpeg] disable libdrm (google#11632)

because of "error while loading shared libraries: libdrm.so.2: cannot
open shared object file: No such file or directory"

Alternatively we can copy that to the lib directory like it seems done
with libz/bz2

google#11629 depends on this but it
seems even on its own some things seem to fail without this
