Add /sys/module/name/notes

This patch adds the /sys/module/<name>/notes/ magic directory, which has a
file for each allocated SHT_NOTE section that appears in <name>.ko.  This
is the counterpart for each module of /sys/kernel/notes for vmlinux.
Reading this delivers the contents of the module's SHT_NOTE sections.  This
lets userland easily glean any detailed information about that module's
build that was stored there at compile time (e.g.  by ld --build-id).
