- Bump version: 9.24.15 → 9.24.16

- Fixed regression in compression detection
The change from 282529de8f612dee32d54ee868c2365dcd829220
Introduced a bad regression. The assumption was made that the
xz tool could be used to detect if a file is compressed or not.
However, this requires the file to be locally present. In the
scope of the method call is_compressed() and within a remote
deployment e.g PXE this is not the case. Therefore the former
way to "detect" the compression according to the .xz postfix
of the source filename was restored. In addition the function
name was changed to is_xz_compressed() because that's what the
method can do and not more. This Fixes #2015

- Added debug option --debug-run-scripts-in-screen
Instead of running scripts in screen if the --debug switch is
set, we allow to explicitly switch on this behavior via
a new option. This Fixes #2010

- Change packages target for bootincludes
Packages marked with bootinclude="true" will be added to the
referenced kiwi boot image description if the initrd_system
is set to "kiwi" instead of "dracut". The package marked was
primarily added to the type="image" section and got only
added to the type="bootstrap" section if no image type section
existed. However, it has turned out that this approach has
the disadvantage that packages which must be installed as
part of the bootstraping (e.g certificates) cannot be handled.
This commit changes the behavior of the bootinclude to include
the package always to the type="bootstrap" section.
