Documentation: security-bugs.rst: update preferences when dealing with the linux-distros group

commit 4fee0915e649bd0cea56dece6d96f8f4643df33c upstream.

Because the linux-distros group forces reporters to release information
about reported bugs, and they impose arbitrary deadlines in having those
bugs fixed despite not actually being kernel developers, the kernel
security team recommends not interacting with them at all as this just
causes confusion and the early-release of reported security problems.
