uspot: add version check override

None of the uspot executables (radius-client, uspot, uspot-das) expose
the package version via --version or --help flags. This causes the
generic CI tests to fail with "No executables in the package provided
version".

Add a test-version.sh to skip the version probe for the uspot,
uspotfilter and uspot-www subpackages.
