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.
