[Buildroot] [PATCH] support/graph-depends: fix out-of-tree usage

graph-depends calls make to get the list of packages, and the
dependencies of each package.

When called out-of-tree, the Makefile is a wrapper that calls
the real Makefile, so make will spit out a line like:
  make -C /path/to/buildroot O=/path/to/build-dir show-targets

which graph-depends wrongly believes is part of the target list.

Be silent when calling make, as we really only want the target
and dependency lists.

Note we do not silence the Makefile wrapper, because it can be
usefull to see what buildroot dir is being used during the build.
For example, I happen to have a few buildroot clones, and seeing
the one being actually being used allows me to be sure I am not
using the wrong once.
