[Buildroot] [PATCH] core/pkg-generic: store file->package list for staging too

Currently, we store the list of files installed in target and associate
each of them to the package that installed it.

However, we sometime may need to know what package installed which file
in staging too, for example to debug header collision.

Enhance the step instrumentation to also generate the list for staging.

Only redirect once, not for each added file.

Also remove the intermediate files.
