Wainer dos Santos Moschetta e5c710e833 packaging/qemu: Build and package completely in the container
Currently QEMU is built inside the container, its tarball pulled to
the host, files removed then packaged again. Instead, let's run all
those steps inside the container and the resulting tarball will
be the final version. For that end, it is introduced the
qemu-build-post.sh script which will remove the uneeded files and
create the tarball.

The patterns for directories on qemu.blacklist had to be changed
to work properly with `find -path`.

Fixes #1168
