[Buildroot] [PATCH 3/3 v2] core/pkg-generic: store file->package list for staging and host too

[Yann E. MORIN <yann.morin.1998@free.fr>]

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/, for example to debug header collision, or in host/, to
debug what package installed what host tool.

Enhance the step instrumentation to also generate the list for staging/
and host/.
