package/x11r7/xlib_libxshmfence: disable on riscv32

Browse Source 
xlib_libxshmfence unconditionally uses SYS_futex which raises the
following build failure on riscv32:

xshmfence_futex.h:58:17: error: 'SYS_futex' undeclared (first use in this function); did you mean 'sys_futex'?
   58 |  return syscall(SYS_futex, addr1, op, val1, timeout, addr2, val3);
      |                 ^~~~~~~~~
      |                 sys_futex
