[PATCH] rteval: kcompile: Fix source tarball argument handling

[Valentin Schneider <vschneid@xxxxxxxxxx>]

Kcompile._WorkloadSetup() looks for a "tarball" and "tarfile" entry in
the CfgSection, but I couldn't find a single setter for thoses. The
only way for a user to specify a file is via --kcompile-source, which
doesn't seem to be actually used by the module.

Make Kcompile actually use --kcompile-source.
