When compiling jailhouse with BR2_PACKAGE_JAILHOUSE_HELPER_SCRIPTS=y,
build is failing with error:
Traceback (most recent call last):

ValueError: Empty module name
This is due to a missing dependency on the target python3 package.
Jailhouse Python scripts are using setuptools with host-python3 which
reads its sysconfig data from the target-python3. See:
https://gitlab.com/buildroot.org/buildroot/-/blob/2024.08.1/package/pkg-python.mk?ref_type=tags#L33
If the target python3 is not installed, this get expanded as an empty
string, leading to this "ValueError: Empty module name" error.
Pure Python packages which are using the python-package infrastructure
usually get this dependency automatically from:
https://gitlab.com/buildroot.org/buildroot/-/blob/2024.08.1/package/pkg-python.mk?ref_type=tags#L295
Here, the jailhouse package rather uses the generic-package
infrastructure, then installs the Python scripts (if enabled) with
dedicated macros. This is why the target python3 is needed.
This commit fixes the issue by adding this missing dependency.
