Makefile: run privileged tests without -check.vv
Makefile: run privileged tests without -check.vv

Historically, all packages containing privileged tests have made use of gocheck
in one way or another, which takes care of declaring the 'check.vv' flag in
the test binaries of those packages.

However, due to the removal of the priv-test package filtering mechanism in a
prior commit, the test run now also contains packages that don't use gocheck,
resulting in an error due to the -check.vv flag not being known in all
packages.

This patch removes -check.vv from privileged test runs, as using gocheck should
not be a requirement for writing tests.
