All list_installed_packages does is print a list of the packages; if you just 
add it to ROOTFS_POSTPROCESS_COMMAND the output will be going into the log file 
for the image task which is probably not what you want. If you wanted to 
proceed with this I think you'd need to redirect the output to some file 
somewhere - this is easily done by instead calling your own shell function and 
then calling list_installed_packages > path/to/some_output_file.txt within it. 
However it sounds like buildhistory will do what you want here anyway.
 
Cheers,
