[PATCH 1/2] remove-net-rules: Add a class to remove net rules from images

[PATCH 1/2] remove-net-rules: Add a class to remove net rules from images

[Chase Maupin]

* Inherit the remove-net-rules class in the TISDK images to remove
  the utility that creates the persistent net rules file.
* This allows moving SD cards between EVMs.

ROOTFS_POSTPROCESS_COMMAND is a list of shell commands/functions - you need to 
terminate it with a semicolon, i.e. R_P_C += "func;"
