[Buildroot] [PATCH 2/2 v2] core/pkg-generic: apply post-prepare hooks before monitoring directories

[Yann E. MORIN]

Monitoring the target/ and host/ directories and so on, will serve to
generate lists of files installed by the packages. Those lists are then
used to generate graphs of the size those package take on the target
for example.

With PPD, we will also want to use those lists to only copy those files
actually installed by each dependencies of a package, recursively.

Currently, those lists are not entirely reliable, as the starting points
are established before we apply PPD fixup hooks. As such, at the end of
a package installation, fixed up files will be found to belong to the
current package, while they were in fact provided by one of its
dependency.

While this does no big harm, if at all, for the size graphs, it will
trigger overwrite detection when we eventually gather packages together
to aggregate a PPD or te final host and target. So, we better have the
lists of files be reliable.

So, we only start monitoring the directories after we apply the PPD
fixups (or seen the other way around for a smaller diff: we apply the
PPD fixups before we start monitoring the directories).
