====================
selftests/vsock: improve vng version and quirk handling

As vng has continued updating, there have been two things in our
selftests that have been affected. One is that newer versions always
emit the vng version warning, and two is that we have a workaround that
is not needed in newer versions.

This series just updates the version handling to allow all newer
versions without warning and version-gates the workaround to only those
versions that don't have the commit that fixed the root cause.

Additionally, we add function for comparing major.minor versions which
is used in both patches.
