package/vlc: disable on riscv32

vlc unconditionally uses __NR_futex resulting in the following build
failure on riscv32:

linux/thread.c:53:20: error: '__NR_futex' undeclared (first use in this function)
   53 |     return syscall(__NR_futex, addr, op, val, to, addr2, val3);
      |                    ^~~~~~~~~~

A patch that fixes this was submitted upstream, but rejected [1].
