Probably /system is mounted as read only.
One quick workaround that you can use is to put your files into
/sdcard, ie /sdcard/iptables and export some parameters like:
export PATH /sdcard/iptables/
export LD_LIBRARY_PATH /sdcard/iptables/lib
Unfortunately, as far as I know, deal with emulator images is a crafty
job. But if you discover how to mount the images and edit the files
you can edit init.rc and change how android mounts /system;
