Updated git submodules

Project: infrautils master 7c5f91ec4d455313937aa068316a6e647e0cfcba

Add common/karaf4 distribution for local testing

This does NOT actually "switch" anything to Karaf 4;
do not worry!  This JUST builds (in 15s) a distribution
which is very handy for local testing of Karaf 4.

based on c/51332 originally by Stephen.
