From: Johannes Berg <johannes.berg@intel.com>
Unfortunately, only very very new versions of spatch are capable
of declaring as an attribute __genl_const which is a define.
However, all the users of this actually follow a really simple
pattern "const struct genl_", so a simple sed line is actually
sufficient for this change.
Introduce the ability for running scripts in the backport and
use it to make this change in a more robust way that doesn't
break whenever changes are made in the code.
