MODSIGN: Add modules_sign make target
If CONFIG_MODULE_SIG is set, and 'make modules_sign' is called then this
patch will cause the modules to get a signature appended. The make target
is intended to be run after 'make modules_install', and will modify the
modules in-place in the installed location. It can be used to produce
signed modules after they have been processed by distribution build
scripts.
