Test suite: take into account that we're shipping the VirtualBox modules only for the 32-bit kernel.

Revision 5d52a82b (diff)

Revert "Changed sysctl option of kernel.perf_event_paranoid to the value of 2."

This reverts commit fa1647cda8d063e340c8c7ebc44e55d62138e47e.

By default, Debian's Linux 4.x sets this sysctl to 3, which is a value
introduced using a small bit of the grsec patch. So let's not hard-code
a less safe custom value.

(Debian's Linux 4.x sets it to 3 by default, which is better than what we're doing on #11421, and also better than explicitly setting the value to 3.)
