[PATCH v2 09/15] bootlinux: fix os detection for 9p build dependency installation

[Daniel Gomez <da.gomez@kernel.org>]

From: Daniel Gomez <da.gomez@samsung.com>

Dependency installation for 9P builds was checking ansible_os_family,
which references the target guest's OS instead of the control host where
packages are actually installed. This caused incorrect packages to be
installed when building Fedora guests on Debian hosts.

Replace ansible_os_family checks with Kconfig distro variables
(distro_debian_based, distro_fedora, etc.) which correctly detect
the control host's distribution. Add fallback defaults to ensure the
variables are always defined for standalone role usage.
