[OE-core] [PATCH] kern-tools: re-enable scc merge command

[Bruce Ashfield]

The ability to merge two branches directly from a .scc file was
dropped during the streamlining of the tools.

As was pointed out by David Vincent <freesilicon at gmail.com>, there is
once again a valid use case for this functionality, so we restore the
capability.

Armin,

This restores old functionality that was dropped due to kern-tools streamlining.
It was reported as missing on morty, and this doesn't impact other functionality
.. so it is worth restoring this, and of course, this also carries forward into
master.

Bruce
