[xaprepare] Add support for newer SparkyLinux (#8684)

SparkyLinux is a Debian-based distribution that's 100% compatible
with its upstream, but it is rebranded and follows its own versioning
scheme.  Add support for SparkLinux detection so that `xaprepare`
can properly detect the required packages.

TODO: the whole Debian detection code has to be refreshed at some
point.
