[Buildroot] [git commit branch/2020.02.x] Makefile: hide commands that build the package file lists at end of build

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=72ec125c16e23b278c5e3109798386fa478a60ee
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x

Since commit 0e2be4db8ab01d479177a3a187c22525752195ae
("package/pkg-generic: make file list logic parallel build
compatible"), the commands executed at the every end of the build
to assemble the list of files installed by the different packages
are visible in the make output. They are quite noisy, and clutter
the output.

The other commands in target-finalize are also hidden using "@",
so we should also do the same for those commands. But that hurts
debuggability, so we use $(Q) (the existing '@'s can be changed
in a followup patch).
