[PATCH v2 3/3] tools/build: Don't print DESCEND messages when executed through kbuild

[Thomas Weißschuh]

kbuild itself does not print the directories it descends into.
When kbuild executes the tools/ build these messages are out of place.

Detect an execution through kbuild and use its printing logic:
Nothing is printed by default, the full command is printed with V=1.

The override logic is part of the tools/ build as kbuild executes
tools/ from multiple places.
