[PATCH v1] tools: fix make rpmball

[Olaf Hering <olaf@aepfle.de>]

Commit 438c5ffa44e99cceb574c0f9946aacacdedd2952 ("rpmball: Adjust to
new rpm, do not require --force") attempted to handle stricter
directory permissions in newer distributions.

This introduced a few issues:
- /boot used to be a constant prior commit
  6475d700055fa952f7671cee982a23de2f5e4a7c ("use BOOT_DIR as xen.gz
  install location"), since this commit the location has to be
  referenced via ${BOOT_DIR}
- it assumed the prefix and the various configurable paths match the
  glob pattern /*/*/*

Adjust the code to build a filelist on demand and filter directories
from an installed filesystem.rpm.

Take the opportunity to replace the usage of $RPM_BUILD_ROOT with
%buildroot, and use pushd/popd pairs.

Fixes: 438c5ffa4 ("rpmball: Adjust to new rpm, do not require --force")
