Update NOTICE with new changes for 1.13

The KCM RPC definitions are copyright KTH/Apple, since it is present
for interoperability with OS X.

Add MS-KKDCP client copyright; alas, it does not match the existing
Red Hat copyrights, since the new code is a 2-clause BSD license, and
there was only a 3-clause Red Hat copyright block present already.

The actual Sphinx output for NOTICE would adjust the wrapping and
indentation of some existing content, but those changes were removed
by hand, so this commit only reflects new added content.
